Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...

Precast Steel-Reinforced Concrete (PSRC) structural frame systems for moment-resisting, comprised of Prefabricated Steel (S) girders and Reinforced Cement (RCC) columns. This system has the advantage inherent stiffness damping during a seismic event. PSRC’s moment-resisting is also known its construction efficiency, lightweight, low cost. Earlier investigations have shown PSRC helpful in design...
