“…Ganapathi, et al [11] found that the compressive strength of brick prisms vary based on the failure pattern, Water absorption, mortar proportion and individual compressive strength of bricks. In this research, triplet brick prisms were cast using different cement mortar proportions 1:2, 1:3 and 1:4 with bond thickness of 10mm and cured for 15 days.…”

Brick masonry plays an important role in the field of construction, signifying the need to study the nature of behaviour of masonry in different conditions and compositions. In this paper, studies on the experimental investigation of material properties, compressive and shear behaviour of brick masonry with different mortar ratios are presented. The material properties are evaluated from compression testing of brick units, mortar cubes and cylinders. Bricks are tested in dry and wet conditions in order to make a comparative study of the material behaviour along all three axes. Compression and shear tests on brick prism triplets with different mortar ratios are performed to evaluate and compare their compressive strength, bond strength and interface behaviour. The results obtained from the compression and shear tests are then evaluated and contrasted. The research carried out would facilitate to evaluate the behavior of unreinforced brick masonry using numerical simulations under shear and compression loading.

“…It is generally accepted that the presence of an opening in a masonry wall, due to functional or ventilation requirements, changes the response of the wall, and consequently affects the structure's behavior. The impact of openings on masonry walls and infills have been studied using numerous analytical simulations [2][3][4][5][6][7][8][9][10]. However, new sophisticated numerical models are required in order to overcome several fundamental issues such as the inherent complexity of non-linear masonry response subjected to both lowand high-level external load applications [11,12].…”

Perforations adversely affect the structural response of unreinforced masonry walls (UMW) by reducing the wall’s load bearing capacity, which can cause serious structural damage. In the absence of a reliable procedure to accurately predict the load bearing capacity and stiffness of perforated masonry walls subjected to in-plane loadings, this study presents a novel approach to measure these parameters by developing simple but practical equations. In this regard, the Multi-Pier (MP) method as a numerical approach was employed along with the application of an Artificial Neural Network (ANN). The simulated responses of centrally perforated UMW by the MP method were validated utilizing full-scale experimental walls. The validated MP model was used to generate a simulated database. The simulated database includes results of analyses for 49 different configurations of perforated masonry walls and their corresponding solid masonry walls. The effect of the area and shape of the perforations on the UMW’s behavior was evaluated by the MP method. Following the outcomes of the verified MP method, the ANN is trained to develop empirical equations to accurately predict the reduction in the load bearing capacity and initial stiffness due to the perforation of UMW. The results of this study indicate that the perforations have a significant effect on the structural capacity of the UMW subjected to in-plane loadings.

“…The in-plane behavior of unreinforced masonry (URM) in¯lled frames has been extensively reported, 1,[13][14][15] whereas few of studies on the behavior of in¯lled RC frames under the combined action of in-plane and out-of-plane loadings has been conducted, though it is a very common case for realistic building structures under seismic excitation. It is questionable that the analytical models that only consider inplane load action can be used to accurately predict the actual structural behavior of in¯lled frame buildings.…”

The structural responses of in¯lled frames subjected to combined in-plane and out-of-plane loadings are usually analyzed by separately applying in-plane and out-of-plane loads. The interaction e®ect of in-plane and out-of-plane loads on the structural behavior of the frames is ignored; thus errors in predicting the actual force-transfer mechanisms and modes of failure of the structures can be incurred. To solve the problem, this paper presents a discrete¯nite element modeling technique, which employs a damage-based cohesive crack representation of fracture behavior of masonry in¯lls, followed by a study on the force-transfer mechanisms and failure modes of the anchored and unanchored in¯lled reinforced concrete (RC) frames subjected to interactive in-plane and out-of-plane loads. The analysis indicates that under out-ofplane loading the diagonal compressive thrust of masonry-in¯ll walls, which is induced by in-plane lateral loading and acts on the walls, may reduce the in-plane load capacity of the RC frame by up to 50% and cause buckling of in¯ll walls. On the other hand, the anchorage can e®ectively prevent the separation of in¯ll walls from the bounding frame and provide stabilizing forces to the walls against buckling.
