In previous studies, experimental and numerical works has been carried out on the effect of infilled frames on steel moment frames; but In previous work on progressive collapse of building system, the main concern has been proposing a substitute load transfer path for the deleted path, and no attention has been paid to the effect of infills in nonlinear dynamic behavior of the structural system. The aim of this study is proposing an appropriate procedure for numerical modeling of infills in steel asymmetric moment frames in progressive collapse analysis. The proposed procedure has been applied to a series of 6 story moment frames with different span size, once without the infills and once more with them. Introduced in terms of equivalent compressive bar, strength of masonry infill is numerically simulated by FEMA-356-Commentrary for Seismic Rehabilitation. The employed software in this research was OpenSees For verification of the proposed numerical modeling procedure results of previous experimental studies have been used. In this paper, endurance time method in loading and dynamic analysis has been chosen to assess progressive collapse. Various scenarios have been considered for column removal to trigger the progressive collapse. Results of dynamic analysis show that the amount of vertical deflection of the studied frames with contribution of infills is significantly less than those obtained without infills.
