In this study the effect of infill masonry on vulnerability of reinforced concrete frames subjected to internal blast loading is investigated. To do so, several 3D reinforced concrete frames with infill which have been designed based on the Iran Concrete Code are subjected to internal blast loading and analyzed using finite element commercial software ABAQUS. Reinforced concrete is assumed to be plastic in behavior while elastic behavior is taken for infill masonry. The infill is modeled as continuum elements using homogenizing theory. It is found that infill masonry effect on the stiffness and elasticity of reinforced concrete frames so neglecting this effect loads to unrealistic assessment of dynamic analysis of in filled RC frames subjected to internal blast loading.
