Abstract: Brick masonry structures are commonly used in world because of its simplicity and economy. However, it is susceptible to failure in earthquakes because of the bricks weak interlocking bonds and brick masonry structures designed mainly against gravity load demand. Therefore, in recent years research work has been conducted to confine the unreinforced brick masonry with reinforced concrete tie beams and column, to improve its seismic performance. This enhances both the lateral resistance and stability of the entire structure, to perform as one mass unit against the lateral forces. However, the effect of confining brick masonry through reinforced concrete member has been evaluated in the past only on testing single cantilever walls or single room. Therefore, this research work aims to evaluate its influence on large structures i.e., highlight its limitation and afterward mitigate the damages by introducing external FRP strengthening techniques. The structures configuration is based on the observation made in Pakistan’s rural areas where mostly brick masonry structure. Confined brick masonry walls are subjected to quasi static lateral loading, afterwards retrofitted with FRP and tested again. The test result discussion includes load response behavior, stiffness degradation, energy dissipation and damage indices.

Abstract:
Many buildings in Indonesia were damaged during the earthquake, especially non-engineered brick walls building. One example of non-engineered brick walls building is Bendung Village Head Office in Serang, Banten, which was damaged by the 2019 Pandeglang earthquake. This building was built without reinforced concrete beams and columns known as unconfined masonry buildings. In this study, the building will be redesigned with ETABS software to determine the similarities between the structural weaknesses from ETABS and the actual damage. The results of the structural analysis give a time period of 0.814 seconds, a base shear force of 195.5 kN, and a stress on the wall that is 50% similar to the real damage. Then, the same building was designed following the rules and regulations for earthquake resistant buildings in Indonesia so that it became a confined masonry building. The result is a time period of 1.586 seconds, a base shear force of 114.2 kN, and a brick wall that is not damaged when exposed to earthquake loads. However, the dimensions and reinforcement of beams and columns that comply with the minimum requirements for earthquake resistant buildings in Indonesia need to be enlarged because their strength capacity is exceeded by the working load.

Abstract:
For further study on effective seismic design requirements of masonry structure, two masonry buildings were designed and constructed according to common structure style in towns and villages. Two full-scale buidings were subjected to earthquake using pseudo-dynamic test and quasi-static test. This paper presents crack propagation of masonry structure, hysteretic behavior, deformation and stiffness degradation under horizontal seismic action. In this experiment, deformability and ultimate bearing capacity of confined masonry (CM) with tie-column and ring-beam is higher than common brick structure (BM). Confined masonry (CM) wall maintain integrity due to constraint of tie-column and ring-beam. These tests verify that tie-column and ring-beam system is an effective seismic requirement to enhance seismic performance of masonry structure.

Abstract:
A two-story masonry housing model was made in this paper. According to Intensity 7, adjusted Northridge record was selected to be the ground motion input in the pseudo-dynamic test. Pseudo-dynamic test and pseudo-static test were carried out to investigate the seismic behavior of the model structure. The time-history curves of the acceleration, velocity, displacement and restoring force of the structural response were obtained besides the time-history curves of the measuring points of the structure. Also the steel strain of the tie-columns and the hysteresis loops of the structure were obtained. The result shows multi-story confined masonry structures possess superior seismic performance if coordinated with the provision specified in the current compulsory design code and it can continue to use after appropriate dressing under the rarely earthquake.

Abstract:
In order to investigate the seismic behavior include hysteretic curve, skeleton curve and stiffness degradation, four masonry structures with different details are tested under pseudo-dynamic test and low cycle lateral load test. One kind of full-scale building is confined masonry with tie-column and ring-beam. Other is common brick masonry. Test results indicate that the tie-column and ring-beam play an important role for developing higher resistance and better deformability. And tie-column and ring-beam can effectively confined brick wall to improve the seismic performance of masonry structure. The stiffness degradation curves are similar. The stiffness degradation is modeled as a function of the effective stiffness and lateral displacement.

Abstract:
Non-engineered confined masonry dwellings are characterized by having different masonry units. One of the most common cases in the Lima Metropolitan Area is that this type of dwelling has its first floors with handmade solid units and upper floors are composed of industrial horizontal hollowed (tubular) bricks. Nonlinear static analysis by the incrementally increasing loading pattern is inadequate to estimating earthquake response of structures with height irregularity, such as non-engineered confined masonry dwellings, because the loading pattern changes during the history of reversal loads due to damaging earthquakes. This paper presents the effect of nonlinear static analysis using adaptive loading patterns in confined masonry dwellings when the type of masonry units changes drastically. Nonlinear static analyses are applied using non-adaptive and adaptive displacement-based pushover procedures. A series of nonlinear time history analyses are also conducted to measure the error in the estimation of the seismic response. The adaptive loading pattern is based on displacement approximation by the modal analysis at each step of incremental-increasing loads. The load pattern is updated considering the modal analysis of an equivalent linear model using the equivalent stiffness of the structure at the secant of the maximum previous response. The application of the adaptive loading pattern in nonlinear static analysis significantly approximates the earthquake response of confined masonry dwellings with height irregularity provided by the change of masonry bricks.

For further study on the influence of ground motion on the seismic performance of brick masonry structure, two masonry buildings were designed and constructed according to common structure style in towns and villages. Two full-scale buildings were subjected to different earthquake motion using pseudo-dynamic test. The earthquake motions are artificial earthquake motion and strong motion recording. This paper presents hysteretic behavior and deformation under horizontal seismic action. Crack propagation of masonry structure is analyzed. These tests verify that displacement response of masonry structures under different ground motion is pretty much the same. Tie-column and ring-beam can effectively confined brick wall. The cracks are mostly diagonal cracks caused by shear failure.

Abstract:
Cavity walls structure is unsuitable in cold area for its faultiness of poor heat-insulating property. But the cavity walls constraint masonry construction is suitable in cold area for its high heat-insulating property. Studies are carried as setting up the restoring force model of the cavity walls confined masonry structure and analyzing the dynamic time-history of cavity walls constraint masonry structure under 7 degrees small earthquake, middle earthquake or large earthquake through EL centro wave, TALF wave, Ninghe wave and Qian'an wave, which indicates that cavity walls constraint masonry construction can satisfy seismic demand of 7 degree quake. Finally, the formula for calculating the interlayer displacement of cavity walls confined masonry structure near collapse is put forward and the counting result is compared with that of dynamic time-history analyzing, which shows that the accuracy of this formula is high enough to be used for analyzing the seismic performance of cavity walls constraint masonry structure.

Abstract:
According to current engineering practice, Confined Masonry (CM) buildings are weak in earthquake resistance and difficult in post-quake restoration. A new form of structure, i.e. Hybrid Masonry – Reinforced Concrete Structure (HMRCS), is investigated. By slightly increasing the sizes and reinforcement ratios of the RC members, i.e. beams and columns, which normally only act as confinement in a CM structure, now play an essential role in resisting the gravity load in HMRCS, while the masonry wall mainly resists the lateral earthquake load. To investigate the seismic-resistant behavior, pseudo-static tests on two full-scale HMRCS specimens were conducted, and the measured hysteretic curves were analyzed. Finite Element (FE) simulation was performed to verify the working mechanism and seismic response of the HMRCS specimens. The lateral displacement ductility factor obtained from the experimental results can fully satisfy the seismic requirement of structures. Therefore, HMRCS is reliable if its RC frame members and masonry walls are designed properly. Furthermore, the feasibility of using FE software to study the proposed HMRCS has been validated by comparing the experimental and simulation results.

Abstract:
This research investigates the nonlinear behavior of scaled infilled masonry (IFM), confined masonry (CM), and reinforced concrete (RC) structures by utilizing and validating two tests from the literature as benchmarks. The validation was based on a comparison with the pushover results of small-scaled physical tests and their numerical modeling. Numerical modeling of small-scale (1:4 and 1:3) IFM, CM, and RC models has been carried out with Finite Element Modelling (FEM) and Applied Element Modelling (AEM) techniques using SAP2000 and the Extreme Loading for Structures (ELS) software, respectively. The behavior of the structure under lateral loads and excitations was investigated using nonlinear static (pushover) and nonlinear time history (dynamic) analysis. The evaluation of the pushover analysis results revealed that for IFM, the %age difference of tangent stiffness was 4.2% and 13.5% for FEMA Strut and AEM, respectively, and the %age difference for strength was 31.2% and 2.8% for FEMA Strut and AEM, respectively. Similarly, it was also calculated for other wall types. Dynamic analysis results from FEM and AEM techniques were found in the fairly acceptable range before yield; however, beyond yield, AEM proved more stable. Finally, the results also showed that the numerical study can be utilized for the evaluation of small-scale models before performing the physical test.

The aim of this article is to use artificial neural networks (ANN) to perform the structural design of confined masonry buildings. ANN is easy to operate and allows to reduce the time and cost of seismic designs. To generate the artificial neural network, training models (traditional confined masonry designs) are used to identify the input and output parameters. From this, the final architecture and activation functions are defined for each layer of the ANN. Finally, ANN training is carried out using the backpropagation algorithm to obtain the matrix of weights and thresholds that allow the network to operate and provide preliminary structural designs with a 10% margin of error, with respect to the traditional design, in the dimensions and reinforcements of the structural elements.

Abstract:
Excessive economic loss and large social impact, due to extensive damage and operational problems in aseismic structures, has been observed following recent earthquakes. This situation is leading to the formulation of a new design paradigm in seismic-engineering. Performance-based design, addressing life-safety, damage-control and functionality issues, is expected to supersede in the near future the current prescriptive serviceability/life-safety approach. In this context, the observed extent of damage in masonry structures, as a consequence of recent moderate and strong earthquakes, seems to disqualify this traditional material in a performance-based environment. Masonry-structures with low density of lateral-force-resisting masonry-walls are among the buildings most likely to be damaged by moderate and strong earthquakes. The use of rocking walls is proposed here as an alternative to improve the seismic performance of these kind of buildings without having to give up the masonry as an integral part of the structure. It was found that rocking confined-masonry walls with hysteretic-energy-dissipators at their base can be reliably designed to match target drifts, which are closely correlated to the extent of the damage in a building. It is shown in this thesis that hysteretic-energy-dissipators can provide a reliable energy-dissipation source that allows the seismic design of this sort of structures with any of the new methodologies proposed to meet seismic performance-objectives, A design procedure adapted from the Direct Displacement Method is developed in the core of this thesis. A prototype structure is designed with the proposed method and a reduced-scale model is built and tested dynamically in a shake table. The experimental results confirmed that rocking walls can be successfully adapted to confined masonry structures. A numerical analysis is also conducted here, with good matching of the experimental results, providing a new tool to deepen the understanding of this system.

Abstract:
Hoy en día existen diversas estructuras en la que se ha dado la aplicación del concreto liviano estructural, por lo que empresas contratistas apuestan por agregados livianos para fabricar concreto liviano de alta resistencia y que cumpla con sus requisitos de diseño. Estos estudios comenzaron a principios de la década de 1980, con óptimos resultados en 1992. Como resultado de todos estos aportes, la información de diseño se ha convertido al alcance de muchos profesionales, y ha permitido que el concreto liviano sea utilizado en alta resistencia y alta durabilidad (Hoff 1992). Es por ello mismo, que nuestra investigación propone el uso de un concreto liviano estructural con perlita de poliestireno expandido en un sistema de albañilería confinada. Este estudio comprende la elaboración del diseño de un concreto liviano estructural; en primer lugar, se investigó un rango apropiado de perlita ya que según Thanon y Jihad (2016) señalan que para obtener óptimos resultados en resistencia a compresión la dosificación de perlita debe variar entre un intervalo de 13-23% ,y es por ello mismo que se escoge trabajar con un porcentaje de 16 % de perlita de poliestireno expandido, pero para términos de comprobación en las propiedades térmicas, también se diseñó con 26% y 36% de perlita; en segundo lugar, para proceder a realizar el diseño del concreto se diseña en base a los requisitos mínimos que establece ACI 318 y con referencias en ACI 211R, la cual interviene en ciertos parámetros para obtener las características de un concreto liviano estructural.
Today there are various structures in which there has been the application of lightweight structural concrete, so contractor companies are committed to lightweight aggregates to manufacture lightweight, high strength concrete that meets its design requirements. These studies conducted in the early 1980s, with optimal results in 1992. As a result of all these contributions, design information has become available to many professionals, and has allowed light concrete to be used for new applications and novelties where high strength and high durability are desirable (Hoff 1992). That is why our research proposes the use of a lightweight structural concrete with expanded polystyrene bead in a confined masonry system for single-family homes. This study includes the development of the design of a lightweight structural concrete; First, a range of bead was investigated since according to Thanon and Jihad (2016) it was pointed out that to obtain optimum results in compressive strength the dosage of perlite must vary between a range of 13-23%, and that is why same that it is chosen to work with a percentage of 16% expanded polystyrene perlite, but for terms of checking the thermal properties, it is also designed with 26% and 36% perlite; secondly, to proceed with the design of the concrete, it is designed based on the minimum requirements established by ACI 318 and with references in ACI 211R, the quality of intervention in specific parameters to obtain the characteristics of a lightweight structural concrete.

Las Redes Neuronales Artificiales (RNA) se han desarrollado en el campo de ingeniería estructural cada vez más con el paso de los años, esta herramienta trata de simular el comportamiento de las neuronas biológicas permitiendo adaptarse a cualquier entorno y resolver diferentes tipos de problemas. En la presente investigación, se aplica al diseño estructural de viviendas de albañilería confinada a estructuras regulares con una geometría rectangular en planta. La aplicación de la red neuronal en este campo nos permite ahorrar tiempo y costos de diseño, así mismo, solo se requiere de personas con un conocimiento básico de manejo de computadoras o aplicativos móviles para la operación de la red neuronal. De este modo, es más sencillo poder otorgar diseños estructurales preliminares a usuarios con escasos recursos económicos que deseen construir viviendas de albañilería confinada. En la presente investigación, se aplican las redes neuronales para el diseño estructural de viviendas de albañilería confinada de 1 a 4 pisos ubicadas en los distritos de Lima con perfil de suelo tipo S1. Para ello, se realizó el diseño de 33 viviendas que cumplen con las especificaciones del Reglamento Nacional de Edificaciones (E020, E030 y E070), estos diseños se usaron como modelos de entrenamiento para el proceso de aprendizaje de la red neuronal y de esta manera se obtuvo un modelo de RNA capaz de diseñar viviendas de albañilería confinada con un error menor al 10%.
Artificial Neural Networks (ANN) have been developed in the field of structural engineering more and more over the years, this tool tries to simulate the behavior of biological neurons allowing to adapt to any environment and solve different types of problems. In the present research, it is applied to the structural design of masonry houses confined to regular structures with a rectangular geometry in plan. The application of the neuronal network in this field allows us to save time and design costs. Likewise, it only requires people with basic knowledge of computer handling or mobile applications for the operation of the neuronal network. In this way, it is easier to provide preliminary structural designs to users with limited economic resources who wish to build confined masonry housing. In the present investigation, the neural networks are applied for the structural design of confined masonry houses from 1 to 4 floors located in in Lima districts with soil profile type S1. For this, the design of 33 houses that meet the specifications of the National Building Regulations (E020, E030 and E070) was carried out, these designs were used as training models for the learning process of the neural network and in this way obtained an RNA model capable of designing confined masonry houses with an error of less than 10%.

Abstract:
Buildings are our basic needs. It protect us from rain, sun, theif e.t.c. We spend most of our time in a building whether it is residential, commercial, institutional, industrial. In Damage or collapsing of such types of vital structures leads to a lot of risk for human lives & results in monetary loss. So, the building should be earthquake resistant. One of the reasons of failure of structure is earthquake. It is found that the reasons behind these collapses are mostly due to the poor construction practices and substandard practices involved in the construction of building. As a structural engineer our duty should be to improve the seismic performance of structure with keeping economy in mind. Confined masonry structure is a construction technology/typology in which first wall are constructed, followed by column and beam. It is similar to RCC and masonry structure in appearance but different in resisting the earthquake load. Due to the lack of relevant design and construction standards, confined masonry construction is currently not practiced in India. However, several initiatives have been launched to promote confined masonry construction over the last ten years. This paper presents the seismic analysis of confined masonry structure using ETABS. Response spectrum method is used for analysis to study the in plane and out of plane behaviour under earthquake loading in seismic zone v. Effect of wall density and shape of column on the seismic performance of confined masonry structure has been also studied. To study the effect of wall density, analysis is done for 110 mm wall, 150mm wall and 230mm wall. To study the effect of shape of column, rectangular and square column is used. Performance of confined masonry and RC frame structure has been also studied. Results are compared on the basis of maximum storey displacement, max storey drift, base shear, overturning moment, modal mass participation ratio. With the study it has been observed that by increasing the wall density seismic performance of confined masonry structure has been increased. In CMS, it has been observed that max storey displacement and drift was less but overturning moment & base shear was more as compare to RC frame structure.

As construções em alvenaria representam uma parte importante do legado construído e cultural do passado, mas também uma solução sustentável para o futuro. Esta é a principal premissa que motivou este trabalho, assim como o desenvolvimento significativo verificado na indústria de produtos para alvenaria nos últimos anos, apesar do panorama atual em que o material alvenaria é essencialmente usado em paredes de preenchimento das estruturas. Neste trabalho estudam-se as possibilidades de construção e o cálculo moderno de estruturas em alvenaria. É apresentado o estado da arte de procedimentos de cálculo sísmico, os quais derivaram sobretudo da experiência acumulada na observação pós-sismo na ex-Jugoslávia e em Itália. Nestes países verificou-se uma grande preocupação na avaliação sísmica de estruturas existentes e na continuidade da construção com alvenaria estrutural, através da realização de amplos estudos experimentais, do desenvolvimento de ferramentas de simulação analítica, da elaboração de normas para cálculo e da disponibilização de software apelativo. Os procedimentos e ferramentas desenvolvidos para aplicação baseiam-se, em geral, no uso de métodos de macro-elementos para análise pushover, com uma verificação da segurança baseada em desempenho. Neste trabalho, estas ferramentas são comparadas e avaliadas, sendo também proposto um método simplificado para análise da resposta global de edifícios, o qual tem em consideração a capacidade inelástica das estruturas. Visando a melhoria do comportamento sísmico de estruturas em alvenaria, é feito um estudo aprofundado da tipologia de alvenaria confinada, para a qual são propostos modelos numéricos e analíticos para cálculo sísmico. Finalmente, são apresentados vários casos de aplicação, incluindo a avaliação sísmica de um edifício histórico, a comparação de diferentes tipologias estruturais na construção de um edifício unifamiliar, e a aplicação das ferramentas modernas de análise no projeto de construção nova em alvenaria. As ferramentas usadas demonstram fiabilidade e robustez computacional, e permitem comprovar a viabilidade e as vantagens de construção com estruturas de alvenaria, tendo em conta um futuro mais sustentável.
Masonry construction represents an important part of the built and cultural heritage, but also a sustainable solution for the future. This is the main reason for this work, jointly with the recent relevant developments in the masonry industry, despite the fact that presently masonry is mainly used as infill of structures. This work addresses the possibilities of construction and modern design for masonry structures. First, a state-of-art of procedures for seismic design is presented, which were derived mainly from the post-earthquake experience in former Yugoslavia and Italy. In these countries a great effort was made to assess existing structures and to keep construction with structural masonry alive, namely by carrying extensive experimental and analytical studies, jointly with the development of modern codes and easyto- use software. The procedures and tools developed for practitioners have been generally based in the use of macro-element methods for pushover analysis, which establishes a framework of performance-based safety assessment. In this work, these tools are compared and evaluated, being also proposed a simplified method for global analysis of buildings that considers the inelastic capacity of masonry structures. The confined masonry typology is studied as an improvement to the masonry structures, developing numerical and analytical models for seismic design. Finally, several case studies are presented, namely the seismic assessment of a historical building, the comparison of several typologies for construction of modern housing, and the application of modern design tools for new masonry buildings. The used tools presented reliability and computational efficiency, which allowed verifying the practicability and advantages of structural masonry, aiming at a more sustainable future.

Abstract:
Masonry is a composite material, and its behavior shows that its weaknesses lie in the minimum resistance of its components and the characteristics of the interfaces between them. Ceramic brick masonry has technological characteristics that make it suitable for housing and building functions. The bricks, of reduced dimensions and joined with mortars of variable characteristics, have the advantage of adapting to almost all construction projects considering the influence of the environment on their service life. The investigation of the structural behavior of masonry has had very significant advances in the laboratory during the last mid-century, which has allowed numerical modeling of the behavior of the material and validation of failure modes under seismic actions. The behavior of heritage masonry with thick walls differs greatly from simple masonry using conventional techniques and materials. These differences in behavior have only been confirmed through numerical simulation contrasted with experimental research. This chapter presents the numerical modeling used for simple and confined masonry with reinforced concrete and for very thick heritage masonry, using the finite element method validated with full-scale laboratory experiences.

Abstract:
Seismic retrofit of existing structures is an extremely important topic in the field of earthquake engineering. For strategic structures such as school and military buildings, bridges and infrastructures in general, the expected performance level is further raised compared to conventional structures to guarantee two fundamental targets: to resist the ultimate design seismic action corresponding to the life safety limit state and to guarantee immediate occupancy after an earthquake event. This means no damage to the structural elements as well as protection of internal equipment from excessive accelerations. Structure functionality is therefore the minimum acceptable level of retrofit for strategic structures. In case of masonry buildings located in medium-high seismicity zones, conventional retrofit (i.e. wall-to-roof and wall-to-floor anchorage, out-of-plane wall bracing, diaphragm strengthening) does not allow to fully achieve the above objectives. Furthermore, the application of these techniques causes an important and invasive impact on the structure, distorting the building on both architectural and functional level. Base isolation is a technical solution that allows to drastically reduce the seismic demand on the structure using special anti-seismic devices characterized by high horizontal flexibility. This paper describes the application of seismic isolation technique to protect the “Giacomo Matteotti” school building, located in the city of Gubbio, Italy. The building was built in the 1940s, and it is made of cast stone and bricks and reinforced concrete-hollow tiles mixed floors. The building has three floors, a total area of 6.000 m2, an inter-storey height of 4 m and a total volume of about 23.750 m3. The City of Gubbio (Umbria region, Italy), is located in an area where strong earthquakes can occur, with expected peak ground acceleration on rock soil equal to 0.29g for 475 years return period (i.e., 10% exceedance probability in 50 years). For the base isolation system, Freyssinet has supplied 94 anti-seismic rubber isolators ISOSISM® type HDRB-H 550x155 and 93 flat sliders with confined elastomeric disc TETRON® type CD GL 3000.600.600 in order to reduce the eccentricity between centre of mass and centre of stiffness of the isolation system and consequently the torsional effects on the superstructure. This paper describes the performance characteristics of the isolators with particular attention to the experimental dynamic response. A special focus is given to all the construction phases and details necessary to isolate a masonry structure.

Abstract:
Masonry structures are commonly used for building residential buildings throughout the Balkans and worldwide, in urban and rural areas and areas with seismic risk. For masonry construction in regions with seismic risk, confined masonry (CM) construction offers an appealing alternative to unreinforced masonry (URM) due to its better seismic performance. The numerical simulation of CM is often based on the Equivalent Strut Model (ESM). Such a model provides a very reasonable compromise between accuracy and efficiency and is simple enough for use in design. The purpose of this paper is to compare the results of an experimental shear compression test on a modern CM wall with different ESM models. Five ESM models proposed by various authors are compared. The numerical pushover analyses were performed in the SAP2000 software, and the reference points of the model that gave the best alignment with experimental results were estimated using regression analyses. The results show that the simple modelling of CM walls with an equivalent diagonal strut, which carries load only in compression, can accurately simulate the global seismic response and is suitable for practical applications.
