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