  • Assessment of out-of-plane behavior of rammed earth walls by pull-down tests, Phuntsho Wangmo, Kshitij C. Shrestha, Mitsuhiro Miyamoto, Takayoshi Aoki, International Journal of Architectural Heritage, 13, 273 - 287, 02 17 , © 2018, © 2018 Taylor & Francis. This article reports pull-down tests performed on rammed earth construction in Bhutan. The pull–down specimens involved an old rammed earth building component as well as a newly prepared rammed earth wall. Both the wall specimens were tested in out-of-plane direction. Theoretical rigid body formulation and finite element (FE) models were developed to predict the response of the rammed earth structures under out-of-plane loading. The validated FE model was further extended to parametric study of material and physical characteristics of rammed earth construction and their effect on critical response quantities. The change in elastic modulus showed effect in the pre-cracking phase of the wall. Density of rammed earth on the other hand affected the post-peak response of the rammed earth wall. Furthermore, an increase in the physical characteristics, namely, the thickness of wall and the vertical superimposed load on top of the wall, enhanced the rocking resistance capacity of the out-of-plane loaded rammed earth walls.
  • Full–Scale Pull–Down Tests on a Two–Storied Rammed Earth Building with Possible Strengthening Interventions, Kshitij C. Shrestha, Takayoshi Aoki, Takaaki Konishi, Mitsuhiro Miyamoto, Jingyao Zhang, Noriyuki Takahashi, Phuntsho Wangmo, Takumi Aramaki, Noboru Yuasa, RILEM Bookseries, 18, 1557 - 1565, 01 01 , © 2019, RILEM. This paper reports pull–down tests performed on full–scale two–storied rammed earth (RE) buildings to assess the out–of–plane performance of RE construction in Bhutan. An innovative strengthening technique is also proposed for strength enhancement of the RE walls. The tests involved two types of specimens, an unreinforced RE structure and an identical reinforced counterpart. The pull–down load was applied on top of the facade. The strengthening strategy involved reinforced concrete sections of dowels and wedges inserted between the RE blocks at regular intervals. The wooden floor beams at the first–floor level were also anchored to the RE blocks in the reinforced specimen. Micro–tremor measurements of the structures were done prior to the pull–down tests. A maximum of 59% increment in peak pull–down load was observed for the reinforced RE specimen compared to its unreinforced counterpart. The unreinforced RE wall showed damage to a larger area of façade, whereas, the reinforced RE specimen showed damage to a relatively smaller zone with controlled failure mechanism.

  • Post-earthquake controls and damage detection through structural health monitoring: applications in l’Aquila, Filippo Lorenzoni, Mauro Caldon, Francesca da Porto, Claudio Modena, Takayoshi Aoki, Journal of Civil Structural Health Monitoring, 8, 217 - 236, 04 01 , © 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The paper presents structural health monitoring (SHM) activities performed on some representative cultural heritage (CH) buildings in the city of l’Aquila after the strong earthquake (Mw = 6.3) that struck the Abruzzo region (central Italy) on April 6, 2009. The severity and the extent of damages caused by the earthquake to historical buildings and monument were never reached before in the recent Italian earthquake history. Emergency activities started immediately after the earthquake to protect CH structures, including damage survey and design/implementation of temporary safety measures. Some historic buildings were soon equipped with monitoring systems in order to assess the level of damage and verify the effectiveness of the executed provisional interventions. The paper focuses in particular on two case studies, i.e. the Spanish Fortress and the Civic Tower. The results of preliminary investigations are reported, including damage survey and operational modal analysis for modal parameter identification using ambient vibration tests. 3-year static and dynamic monitoring features, automatically extracted from raw data acquired by continuous monitoring systems, were then processed using a data-driven approach based on regression analysis to filter out the environmental effects. Following this approach data are decomposed into their reversible and irreversible components, the latter being associated with active damaging processes and the residual structural performance of the two buildings assessed.
  • Relationship between fundamental natural periods and structural specifications of lighthouses, Minami Kawase, Takayoshi Aoki, Jingyao Zhang, Daisuke Sato, Journal of Structural and Construction Engineering, 83, (745) 397 - 407, 03 01 , © 2018 Architectural Institute of Japan. All rights reserved. This paper presents the relationship between the fundamental natural periods and the structural specifications of lighthouses, including those made in brick, stone and reinforced concrete. Structural specifications are the structure height, the structure classification, the elevation shape, the plane shape, the foundation type and the weight of the top. According to the correlation analysis, it was indicated that the structure height is related to other structural specifications. In addition, it was shown that the fundamental natural period of the lighthouses could be estimated using only the structure height.
  • Long-term observation of static and dynamic charactes of the Lighthouse - Long-term variations Part 1, Minami Kawase, Takayoshi Aoki, Daisuke Sato, AIJ Journal of Technology and Design, 24, (56) 69 - 74, 02 01 , © 2018 Architectural Institute of Japan. All rights reserved. Structural health monitoring is a method of estimating the presence of the damage of the structure, and its position and degree by the change of static and dynamic characteristics before and after the secular change or the action of external force. However, the static and dynamic characteristics of the actual structural fluctuate on daily, seasonal and diachronic variations basis without depending on damage or not. These characteristics of reinforced concrete lighthouse were observed for about one and a half year by the authors. This paper presents long-term variations of crack widths, inclination angles, temperatures and natural frequencies of this lighthouse.

  • Vibrational characteristics of reinforced concrete building during demolition work (reduction process), Takahito Tsuchida, Katsunobu Yadori, Takayoshi Aoki, AIJ Journal of Technology and Design, 23, (54) 437 - 440, 06 01 , In this paper, we present the experimental results of a series of microtremor measurements of a RC building during demolition work (reduction process) in order to clarify their properties in dynamics. The RC building was reduced from 5 stories + 1 story penthouse to 4 stories. We conducted microtremor measurements before, during and after reduction process. Natural frequencies of the RC building were increased in accordance with its reduction process and strengthening works. Based on the equivalent single degree of freedom system, influence of weight reduction and stiffness increment on natural frequencies by reduction process and seismic strengthening is clarified.
  • Damage detection of multi-story shear buildings due to earthquakes by model updating method, J. Y. Zhang, T. Aoki, Structural Control and Health Monitoring, 24, 04 01 , Copyright © 2016 John Wiley & Sons, Ltd. In this paper, we present a novel model updating method for damage detection of multi-story shear buildings during severe earthquakes. The story stiffnesses are explicitly presented in an incremental manner; this enables a simple and robust algorithm for the purpose of identification of the story stiffnesses. The estimated modal data, including natural frequencies and mode shapes of lower modes, are used in the proposed algorithm; moreover, sensitivity analysis of natural circular frequencies is incorporated to reduce possible errors. The story stiffnesses are identified by an iterative algorithm, and the window shift technique is adopted to present change of the story stiffness due to damages in the buildings during earthquakes. Numerical examples demonstrate that the proposed method is of high accuracy, even when the recorded responses are polluted by a relatively high level of (white) noises.

  • Deformation prediction of brick masonry in coke oven, Noriko Kubo, Takayoshi Aoki, Shunichi Kamezaki, Jun Okada, Tetsu-To-Hagane/Journal of the Iron and Steel Institute of Japan, 102, (12) 669 - 676, 01 01 , © 2016, Iron and Steel Institute of Japan. All rights reserved. Various types of brick masonry are used in the handling and treatment of hot materials in steelmaking processes. Although trouble related to damage of the bricks and joints is an important issue, it is difficult to predict and prevent damage of brick masonry because masonry is characterized by heterogeneity, nonlinearity and nonequilibrium. In this paper, the brick masonry in a coke oven is studied as an example, and a method of deformation prediction under external force is developed as a basic study. First, a compression test of a sample consisting of two bricks with one mortar joint is performed. Second, a part of a heating flue of a coke oven made of bricks is constructed as a test sample, and brick masonry deformation under external force is measured experimentally. Third, a model of the same heating flue in the experiment is prepared, and a numerical elasto-plastic analysis is carried out using the total strain rotating crack model based on the measured mechanical properties. Finally, the experimental and numerical deformation results are compared. The results validated this method of predicting masonry deformation.
  • Structural health monitoring for post-earthquake controls: Applications in l'Aquila, F. Lorenzoni, M. Caldon, C. Modena, T. Aoki, 2015 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems, EESMS 2015 - Proceedings, 162 - 167, 08 03 , © 2015 IEEE. In the last decades structural health monitoring (SHM) has been increasingly applied in the study of Cultural Heritage (CH) buildings, as a key activity to improve the knowledge on their structural behavior and identify the presence/activation of possible damage mechanisms. This knowledge allows engineers to carry out with more confidence and only if necessary a strengthening intervention, and it helps to prevent the execution of intrusive repair works, if not justified by an experimentally demonstrated worsening of the structural conditions. The use of monitoring systems applied under ordinary conditions and installed on CH structures may allow to: (i) validate the functioning of the adopted structural models; (ii) identify ongoing damaging processes; (iii) validate the effectiveness of the strengthening interventions. In case of a seismic event, SHM can furthermore prove its usefulness in order to: (i) evaluate quantitatively the progression of the damage pattern, (ii) carry out effective and urgent interventions if an unsafe displacement patterns is recorded; (iii) define an early warning procedure for the safety of the workers employed in the strengthening interventions. Monitoring can also be effective when implemented on seriously damaged buildings, if the time schedule for the interventions is difficult to be a priori planned. In this framework, the authors designed and installed SHM systems on six representative and emblematic CH buildings in L'Aquila after the devastating earthquake occurred on the 6th of April 2009 in the Abruzzi Region. Two selected case studies (Spanish fortress and Civic tower) report the experience gained on the use of monitoring during the emergency activities after a seismic event. Monitoring and damage detection algorithms have been successfully applied to control the evolution of the seismic-induced damages and verify the effectiveness of the provisional interventions executed immediately after the earthquake.
  • Identification of building damage using vibrational eigenvalue and eigenmode pairs, Kazuma Tago, Takayoshi Aoki, Hideyuki Azegami, Japan Journal of Industrial and Applied Mathematics, 32, 297 - 313, 07 28 , © 2015, The JJIAM Publishing Committee and Springer Japan. The present paper describes a solution to a problem of identifying damage in a building based on experimentally measured vibrational eigenvalue and eigenmode pairs. The healthy rate, which is defined as the stiffness rate with respect to a perfect material, is chosen as the design target to be identified. The range of the healthy rate is restricted to within the range of 0–1. In order to overcome this restriction, we define a function with no restriction on the range defined in the domain of a linear elastic body for a building as a design variable and assume that the healthy rate is given by a sigmoid function of the function of the design variable. The linear coupling of the mean squared errors of vibrational eigenvalues and eigenmodes with respect to the measured values are used as a cost function. The derivative of the cost function with respect to the design variable is evaluated by the adjoint variable method. In order to resolve the identification problem of the damaged area, we use an iterative algorithm based on the $$H^{1}$$H1 gradient method using the finite-element method to obtain numerical solutions. A numerical example using experimental data demonstrates that a damaged area can be identified by the proposed approach.

  • Estimation of vibration characteristics of a lighthouse by microtremor measurements, Minami Hidaka, Takayoshi Aoki, AIJ Journal of Technology and Design, 21, (47) 71 - 76, 02 01 , It is extremely important to obtain reliable information about actual structural and dynamic properties to evaluate the earthquake-resistance performance of a structure. However, examples of vibration experiments performed for a lighthouse are scarce. This study focuses on estimating the dynamic parameters of the Ujina Lighthouse by performing microtremor measurements and forced oscillation experiments. Although some variation is observed between the damping factors obtained from the measurements and experiments, the natural frequencies obtained from both the methods agree well up to higher modes of vibration. Therefore, microtremor measurement is a useful method to obtain reliable dynamic properties simply and easily.
  • Model updating to forecast the dynamic behavior of the Ghirlandina tower in modena, Italy, Donato Sabia, Takayoshi Aoki, Renato Maria Cosentini, Renato Lancellotta, Journal of Earthquake Engineering, 19, 1 - 24, 01 01 , © A. S. Elnashai. Historical masonry towers survive at an alarming angle of inclination and may be in danger of leaning instability due to the lack of stiffness of the supporting soil. Therefore, careful investigation is required to estimate the seismic vulnerability as well as its long-term behavior. These problems require a multidisciplinary approach to properly model the behavior of the structure and its interaction with the supporting soil. This article is intended to contribute to these aspects, by showing how identification analyses can highlight the role of soil-structure interaction, and focuses on the model-updating techniques to forecast its behavior under seismic events.

  • Structural health monitoring of historical buildings: Preventive and post-earthquake controls, Filippo Casarin, Claudio Modena, Takayoshi Aoki, Francesca Da Porto, Filippo Lorenzoni, SHMII-5 2011 - 5th International Conference on Structural Health Monitoring of Intelligent Infrastructure, 12 01 , Structural health monitoring (SHM) has been recently more and more utilized in the study of Cultural Heritage (CH) buildings, as a key activity to increase the knowledge on their structural behavior and to have a deeper insight into their conditions. This knowledge allows engineers to carry out with more confidence and only if necessary a strengthening intervention, and it helps to prevent the execution of intrusive repair works, if not justified by an experimentally demonstrated worsening of the structural conditions.

Monitoring can also be effective when implemented on seriously damaged buildings, if the time schedule for the interventions is difficult to be a priori planned. In this framework, the authors and the university of Padua in collaboration with the officer of the Cultural Heritage Authority, the university of Nagoya (Japan), the National Institute of the Conservation and Restoration (ISCR) designed and installed SHM systems on six representative and emblematic CH buildings in L'Aquila after the devastating earthquake occurred on the 6th of April 2009 in the Abruzzi Region. The selected case studies SHM systems-presented in the paper-report the experience gained on the use of monitoring in "normal" conditions and after the emergency activities following a seismic event.
  • Safety assessment of the Sanctuary of Vicoforte, Italy, Takayoshi Aoki, Noboru Yuasa, Hitoshi Hamasaki, Yoshiaki Nakano, Noriyuki Takahashi, Yasuo Tanigawa, Tatsuhito Komiyama, Tomoyuki Ina, Donato Sabia, Giacomo Vincenzo Demarie, International Journal of Materials and Structural Integrity, 5, 215 - 240, 08 01 , In order to evaluate safety assessment of the Sanctuary of Vicoforte, Italy, a series of non-destructive tests were carried out for diagnostic inspection of its deterioration. Delamination of stone finishing and fresco painting were detected. Dynamic ambient vibration test was carried out and the relevant modes of vibration were identified resorting to the stochastic subspace identification method. The first two natural frequencies of the Sanctuary of Vicoforte were estimated to be about 1.93 Hz and 2.07 Hz in East-West and North-South directions, respectively. Therefore, the dome seems to be vulnerable to severe earthquakes characteristic of the local seismicity such as we experienced in recent years. © 2011 Inderscience Enterprises Ltd.

  • Model updating of a real multi-span masonry bridge, T. Aoki, D. Sabia, D. Rivella, Civil-Comp Proceedings, 83, 01 01 , A 19th century multi-span masonry arch bridge over the Tanaro River, in the city of Alessandria, in the north-western Italy, was demolished and replaced by a new one and its demolition allowed carrying out some destructive test. For the purpose of obtaining the data concerning the dynamic structural properties of the remained two spans bridge, acceleration time histories due to impulsive loading were measured in the two cases, without fill materials as well as spandrels. From the results of dynamic tests, eight fundamental frequencies and mode shapes were identified by ERA (eigensystem realization algorithm) technique. A comparison of the fundamental frequencies and mode shapes determined by ERA technique and the results determined by FEA (finite element analysis) based on IEM (inverse eigensensitivity method) was discussed. © 2006 Civil-Comp Press.

The stability of the airship hangar is now threatened by the differential settlements of its spread footings and a research project is currently underway to strengthen the hangar. In this paper, 1) deterioration of the wall and roof, 2) bar arrangement and its corrosion, 3) depth of neutralization and included chloride ion, 4) fundamental frequency, and 5) monitoring of temperature, inclination of buttress pier, width of the significant cracks and extension of the wire are discussed.
  • FLEXURAL EXPERIMENT OF ACTUAL STRUCTURAL BEAMS USED FOR 33 YEARS(Structure), MOROHASHI Noritaka, YUASA Noboru, AOKI Takayoshi, SAKURADA Tomoyuki, MATSUI Isamu, Aij Journal of TECHNOLOGY and Design, 12, (24) 137 - 142, When a 33-year-old schoolhouse of a university was dismantled, a beam that had been used as a structural member was removed, and its flexural crack properties and flexural load capacity were examined. It was found that the maximum flexural crack width at the main reinforcement position before flexural load was applied had become smaller than the durability limit. On the other hand, the maximum flexural crack width at the service loading after flexural load had been applied was larger than the limit value. The flexural yield load corresponded well to the ultimate flexural strength of the standard for structural calculation of reinforced concrete structures.
  • Dynamic identification of RC building No.5 of the College of Industrial Technology at Nihon University, T. Aoki, N. Yuasa, D. Sabia, D. Rivella, H. Muto, Proceedings of the 10th International Conference on Civil, Structural and Environmental Engineering Computing, Civil-Comp 2005, 12 01 , The present study deals with dynamic identification and model updating of the reinforced concrete (RC) building No.5 of the College of Industrial Technology, Nihon University, Japan. From the results of microtremor measurement by ambient vibration, the fundamental frequencies of the RC building No.5 are estimated to be about 2.76 Hz and 3.56 Hz in longitudinal and span directions, respectively. The natural modes and damping factors are identified by ARMAV (Auto Regressive Moving Average Vectors) model. From the results of model updating based on IEM (Inverse Eigensensitivity Method), the changes of live load and the damaged areas are identified and these correspond well to the removal work and the positions where the destructive tests are applied. © 2005 Civil-Comp Press.
  • A study on users’ sphere model of the interchanges on an expressway, 大橋昭宏, 青木孝義, 小浜芳朗, 都市計画論文集(CD-ROM), 40, (40-2/40-3) 40.2,45-50 - 50, 10 25 , The present study proposes a user's sphere model of interchanges on expressway. Although interchanges should be allocated under various kinds of constraints, the user's sphere of interchanges is determined by the traffic cost including expressway charge, running expense, value of time and the transport cost of the industry shipping in this paper, assuming that drivers choose more reasonable routes to their destinations. In the case of Tomei-expressway, the results of the proposed model corresponded well to the actual state of where roads were equally arranged in the district. The user's sphere model will be more accurate by inputting information of local traffic characteristics such as road network, condition of road network, and number of vehicles on the road.
  • Limit analysis of masonry walls with rectangular openings by equivalent shear panel model, T. Takada, T. Aoki, G. Genovese, Advances in Architecture, 15, 297 - 306, 12 01 , The present study deals with the limit analysis of masonry walls with rectangular openings by an equivalent shear panel model. Many experimental results on masonry walls with rectangular openings subject to both vertical and horizontal loads show importance of shear resistance of wall panels. Based upon these experimental results, in-plane failure patterns of single masonry walls are categorized into a) the shear diagonal crack opening, b) local panel rocking, c) bed joint sliding, and d) full or partial overturning of an entire wall. The equivalent shear panel model can evaluate strength for typical in-plane failure patterns due to earthquake damages. By means of the present model the limit analysis of masonry walls can be formulated as a searching problem for a collapse mode with minimum failure load, to which the genetic algorithm (GA) can be applied. The application of both the present shear panel model and the GA is illustrated in a numerical example of a masonry wall with rectangular openings subjected to constant vertical and incremental horizontal loads.

Relationship between the mix proportion of the mortar, its color, and its water content is clarified. Experimental equation of estimating the mix proportion of the mortar is given and mechanical characteristics of mortar such as compressive strength are obtained.
  • 52 Structural analysis of the dome of Suleymaniye Mosque : Cracks of the main dome, AOKI Takayoshi, Journal of structural engineering. B, (44) 423 - 428, 03 20 , This paper consists of two parts. The first part deals with the investigation of crack pattern of Suleymaniye Mosque. The crack pattern drawings of the main dome are presented here as a brief result of the investigation. The second part covers the Finite Element Analysis of the dome. As a preliminary step, I analyzed the dome alone, applying three-dimensional models composed of 9-node Heterosis shell elements. Structural characteristics of the dome are considered through material and geometrical non-linear analysis in case of dead load. Analytical results show that the maximum strength of the dome becomes 2.45 times of dead load. The crack development is analyzed comparing with the one investigated.
  • 57 Influence of carbonization on strength development of mortar used for Hagia Sophia and some related structures, AOKI Takayoshi, ITO Norio, KADOYA Terunori, Journal of structural engineering. B, (44) 471 - 476, 03 20 , For the purpose of obtaining the data concerning structural characteristics of Hagia Sophia and some related structures, a series of micro tremor measurements, material test, and structural analyses are carried out. This paper deals with a series of material test of the mortar under the condition of carbonization. Test results show that compressive strength and tensile one of the carbonated mortar are obtained 2.3 to 3.6 times and 1.7 to 3.4 times of the values of the non-carbonated mortar, respectively. The dynamic modulus of elasticity of the carbonated mortar is also estimated 1.8 to 2.7 times of the value of the mortar before carbonization.
  • 72 Strength and Young's modulus of mortar used for Hagia Sophia and some related structures, AOKI Takayoshi, ITO Norio, KADOYA Terunori, HIDAKA Kenichiro, Journal of structural engineering. B, (43) 635 - 640, 03 20 , For the purpose of obtaining the data concerning structural characteristics of Hagia Sophia and some related structures, a series of micro tremor measurements, experiments, and structural analyses of them were carried out. This paper deals with a series of experiments of the mortar as well as of the masonry which consists of brick and mortar. From the results of experiments, the tensile strength of the mortar is estimated as 1/10 of compressive strength. Static and dynamic modulus of elasticity for mortar and masonry corresponds well to the Young's modulus of the masonry used for Minarets determined by the micro tremor measurements.
  • 73 Deformation and seismic strength of the dome of Hagia Sophia, AOKI Takayoshi, KATO Shiro, ISHIKAWA Koichiro, HIDAKA Kenichiro, Journal of structural engineering. B, (43) 641 - 646, 03 20 , For the purpose of obtaining the data concerning structural characteristics of Hagia Sophia, we have carried out a series of micro tremor measurements, experiments, and structural analyses of the dome. From the results of Finite Element analyses, the oval displacement pattern of the base of the dome is in accordance with the actual state of the structure. Comparison of the displacements of two transverse arches, N-S arch and double arch, seems to give an information that the north to south arch is weaker than the west to east arch. According to our structural analyses, the dome of Hagia Sophia seems to be vulnerable to severe earthquakes.
  • 2253 Strength of Mortar Used for Hagia Sophia and Some Related Structures, AOKI Takayoshi, ITO Norio, コンクリート工学年次論文報告集, 18, (2) 1523 - 1528, 史料に基づきハギア・ソフィア大聖堂に使用されていたモルタルの構成材料の容積比勧砂2,消石灰1,レンガ28と推定した。レンガ粒径0.6mm未満を入れた試験体はα6mm以上を入れたものより圧縮強度が大きくなっているがこれは微細分レンガが試験体内の空隙を埋め密実になっているためである。このことが既にアルベルティの『建築論』で言及されていることは興味深い。また,曲げ弓鍍は圧縮強度の約1/2,引張強度は約1/10であることがわかった。動弾性係数はミナレットの常時微動測定から同定されたヤング係数と良い一致をみた。
  • Vibrational characteristics of Hagia Sophia and some related historical structures based on measurement of micro tremors(SESSION), AOKI Takayoshi, KATO Shiro, ISHIKAWA Koichiro, YORULMAZ Mufit, CILI Feridun, Journal of structural engineering. B, (40) 87 - 98, 03 15 , For the purpose of obtaining the data concerning dynamic structural properties of Hagia Sophia, we have carried out a series of micro tremor measurements on four different levels inside the huge structure and some related historical structures. We conclude that the fundamental frequency is around 2 Hz in both north-south and east-west directions. For three of the four minarets in Hagia Sophia and for two of the four minarets in Siileymaniye Mosque, the micro tremors were also measured and their fundamental frequencies were estimated to be around 1 Hz. From the measurements, the young's moduli of the brick and the stone used for those structures are estimated 2.8 and 6.8(×10^4kgf/cm^2), respectively.

  • Structural Role of the Horizontal Brick Arches of the Dome of Santa Maria del Fiore, 青木 孝義, Reports of the Faculty of Engineering,Nagasaki University, 22, (39) p169 - 186,   1992 07 , The dome of Santa Maria del Fiore consists of two shells, an inner one and an outer one, which are connected by eight massive ribs and sixteen intermediate ribs. The principal rib and the intermediate rib are linked through little horizontal brick arches. As to the structural role of the horizontal brick arches, there are currently four opinions. 1) They are connecting rings, 2) They are load-transmitting rings, 3) They contributed to the self-support of the outer shell during its construction, and 4) Thgy are for their geometrical rather than their structural properties. From the structural point of view, the horizontal brick arches must have been an appropriate contribution to the self-supporting of the outer shell.
