Unreinforced masonry shear walls are often used as the main structural component of masonry buildings responsible for carrying the lateral loads. The lateral and vertical loads lead to tension and shear combined with compression within the masonry wall. Fracture and failure of masonry walls under shear compression is intricate because of the complex interaction of shear failure along the mortar joints and compression failure often at the toe of the wall.
This study covers the modeling and the analysis of unreinforced masonry walls under shear-compression failure. In this study, a simplified micro modeling approach is used wherein the two masonry components: bricks and motar joints are modeled separately. The motar joint, which is the plane of weakness, is represented through interface nodes of zero thickness. The analytical model of Drucker-Prager yield criterion which is a smooth approximation of the Mohr-Coulomb theory is used to model the nonlinear behavior of masonry walls.
The analytical results are verified by comparing the experimental results on a masonry wall under lateral loading. The comparison shows a good agreement between the developed FEM model and the experimental test results. Also, the developed FEM model can predict the cracking pattern of unreinforced masonry shear wall under shear and compression.
