These factors must be considered by design engineer and ensure resistance of the structure against those events. Seismic progressive collapse is one of the causes of serious damages and losses which may happen in events such as earthquakes. In this paper, it is intended to introduce more appropriate brace configuration based on an upper-bound estimation of the probability of seismic progressive collapse in MRF-EBF dual systems designed based on the 3rd edition of Iranian Seismic Code. In fact, in that standard there are only provisions for capacity of moment frames and no detail is given for bracings elements. The study has been concentrated on low to mid-rise buildings with residential and office usage. Results show that for 5-story buildings the best number of bracing bays is as many as 10-20% of the number of building's circumferential bays, and for 8-story buildings best number of bracing bays is as many as 20-30% of the number of building's circumferential bays. Results also show that regular bracing in internal bays are more appropriate for more resistance of the structure against progressive collapse.
