A brick masonry wall is one of the most ancient construction techniques used to build buildings. But nowadays, more focus is on sustainable development and fast construction. Fly ash bricks are used widely in construction. For rapid construction, steel structures are used on a large scale. So, in this paper, we have studied the behavior of infill masonry walls made up of fly ash bricks and cement mortar confined in steel frame by applying in-plane cyclic loading to the infill masonry wall. Moreover, the Same model is modeled in FEM-based software (Abaqus). The cracks pattern was observed, and it highly validates the experimental results. The concrete damage plasticity model was used to model the brick masonry in the FEM model. This study investigates the behavior of masonry walls with 1:3 mortar proportion used in brick masonry, i.e., 1:3, 1:4, and 1:6 (Cement: Sand). And it is observed that if strong mortar (1:3) is used, cracks try to propagate through both bricks and mortar joints. And if weak mortar (1:6) is used, generally separation of mortar and brick joint is observed.
