“…Note that in determination of the compressive capacity of the FT (F YFT ), which is determined considering axial force-flexural moment interaction, the effects of the generated bending moments at the base of this tie is also considered. This assumption is valid considering moments in the form of horizontal cracks at the tensile face in ties have been reported [28,33,[42][43][44][45][46][47][48]. It can generally be concluded that the lower the L/H, the higher the forces and the higher the generated moments in the ties are.…”

Summary This paper addresses the behavior of confined masonry walls with dominating shear failure mode in walls. For this purpose, failure modes of these walls are classified in details. For each failure mode, complete set of analytical‐based relations for deriving parameters related to backbone curves is introduced. Calibrated finite element analyses are utilized as a benchmark for verification of some of the assumptions. The results of the proposed relations are compared with those of several Iranian and non‐Iranian experimental data. Sensitivity analysis is performed in order to understand the effects of important behavioral characteristics of these walls. The results of this study indicate that the proposed relations can accurately simulate behavior of confined masonry walls with dominating shear failure mode regardless of the failure mode in the ties. Moreover, it is concluded that the detailing limitations given in the Iranian Seismic Code are rationally compatible with the behavioral characteristics of confided masonry walls. The results of this study in terms of backbone curves can be utilized as the complementary part to this code. Copyright © 2017 John Wiley & Sons, Ltd.

“…The numerical modeling of masonry walls subjected to inplane loading allows the assessment of the behavior of this system to another excitation, without the need for more tests. It is known that the design criteria and construction techniques for CM walls and masonry infill walls are different, and the effect of the type of connection between the panel and confining elements has been studied [8,13]. However, Torrisi et al [14] established that the responses of these systems to inplane loads are somewhat similar, because the behavior of the system is controlled by the nonlinear response of the masonry wall panels and the surrounding RC elements.…”

“…equivalent to the experimental results for similar CM walls made with solid clay bricks. Wijaya et al [13] studied the influence of the type of connection between the wall panel and RC elements (e.g., grooves at interface of masonry and tie column, continuous anchorage embedded in mortar joint and RC elements). They investigated a reinforced concrete frame with masonry infill.…”

“…In spite of the masonry experimental research programs conducted in many countries [4][5][6][7][8][9][10][11][12][13][14], the behavior of CM walls is still not well known [10], and the results tend to be for the characteristics of structural systems related to regional situations (e.g., construction process, quality of labor, material properties). As noted above, the available information on CM walls in the case of Peru is limited.…”

The experimental results of four full-scale confined masonry (CM) walls subjected to cycling loading are presented. These structural elements are widely used in low-and mid-rise buildings in Peru to take the vertical and lateral loads. The objective of these experiments was to evaluate the cyclic behavior of CM walls constructed with handmade bricks and mortar.The brick units used in the walls were made of clay, and they were considered to be solid components. In the experiment, the dimensions of all the walls were kept constant in all specimens, but the reinforcement ratios of the confining elements (bond beam and tie-columns) were changed. The structural behaviors were examined in terms of the strength, lateral stiffness, dissipated energy, and equivalent viscous damping. Finally, an equivalent macro-model based on an equivalent strut approach with a smooth hysteretic model was calibrated and validated in order to reproduce the behaviors of the CM walls. For this purpose, we used a genetic algorithm (GA) that considered the experimental results of a CM wall. The parameters were applied to the results of the other CM walls to evaluate their applicability.The results of numerical simulations showed good agreement with the experimental results.

“…Mostly these studies are on wall panels submitted to lateral displacement control loading combined in plane normal and shear. Meli [8] carried out tests on confined masonry panels to assess the shear strength, ductility and energy absorption capacity; Bernardini [9] reported the results of tests to clarify issues on stiffness degradation, crack evolution and energy dissipation; Luders and Hidalgo [10] performed cyclic tests in partly and fully grouted CM walls to study the effect of reinforced horizontal mortar joints; Tomazevic and Lutman [11] presented study on seismic resistance of reinforced masonry walls; Sanchez and Astroza [12] studied the behavior under cyclic loading and quantified the confining improvement; Kumazwa [13], Yoshimura [14] studied non-linear characteristics of CM wall with lateral reinforcement in mortar joint at corner part of wall; Yoshimuara [15] again evaluated effect of wall reinforcement subjected to lateral forces at different heights and axial load; Yanez [16] showed the comparison of CM wall panels made of hollow concrete and clay brick masonry unit with four cases of openings; Zabala [17] presented a complete study on CM walls with different column reinforcement; Marinilli [18] presented the results of four full-scale wall panels with 2, 3, and 4 tie columns under reversed cyclic lateral and constant vertical load; Gouveia and Lourenco [6] reported test results on CM walls showing influence of confinement, horizontal reinforcement and different kinds of units; Wijaya [19] presented a complete study on CM walls with grooves at interface of masonry and tie column, short anchor between column-wall and continuous anchorage embedded in mortar joint and RC column and carried out comparative study with reinforced concrete frame with masonry infill. Meanwhile, the knowledge of various parameters of CM walls under cyclic loading is very scanty.…”

Recent earthquakes around the world have resulted in loss of human lives and high economic losses due to poor performance of unreinforced masonry constructions as well as poorly-built reinforced concrete framed buildings. This has necessitated alternative building technologies with improved seismic performance. Confined masonry (CM) construction, has shown excellent behavior during past earthquakes across the world and requires similar skill at a marginally higher cost than that of unreinforced masonry. This paper summarizes the main features of generic construction and gains insight into the behavior of CM elements under earthquake excitations, representing a viable alternative for safe and economical construction in seismic areas. The paper discusses various influential aspects like sequence of construction, properties and type of masonry material, structural configuration, reinforcement detailing in tie column/beam and masonry, panel aspect ratio, interface between concrete and masonry, axial stress, multiple confining column, opening in wall panels and damage pattern etc. along with solution to overcome the limitations.
