Reinforced masonry buildings are technically and economically suitable options for earthquake-pronecountries. Inadequate connections between the components of these structures cause damage anddestruction in an earthquake. Percentage and connection type between wall and concrete slab are themost effective parameters on safety of these buildings. In this article a model for the seismic behaviorof reinforced masonry (RM) building subjected to push-over analysis has been presented. The modelingof the RM structure with concrete slabs has done in ABAQUS, using explicit finite element model. Theproposed finite element model has been verified by comparison with experimental data available in theliterature and then five models including one, two and four story buildings in different situations havebeen modeled. Bending length, distance and diameter of joint bars between the walls and concrete slabhave been investigated and some recommendations in this field have been presented.
