Masonry walls are used extensively as exterior walls to form part of the building envelope and as interior partition in steel or concrete structures. Due to Complexity in analysis and insufficient design information it is not accounted for in current design practices, however only few studies were conducted to comprehend the behavior of masonary wall. In this study a finite element technique was used to model masonry infilled RC frame using concrete brick and flyash brick under cyclic loading using the simplified three-dimensional micro-modeling approach in commercially available FE software ABAQUS. The inelastic behavior of concrete and steel reinforcement bar has been incorporated through concrete damage plasticity model and Johnson- Cook models available in ABAQUS. The simulations were carried on the infilled frame against cyclic loading which was proximity of experimental tests conditions and geometry available in the literature. The simulated and experimental results were compared and found to be in good agreement with each other. Thus, from the results it can be inferred that infilled wall with concrete brick masonry assemblage performed better than flyash based infilled wall system.
