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...

Seismic vulnerability of reinforced concrete (RC) buildings is strongly influenced by beam-column joints. Horizontal and vertical structural members converge in joints, as extremely delimited areas where the internal forces core reinforcing bars have elevated stress gradients. In order to fully understand seismic behavior RC related failures T- X-shaped joints (external corner internal-position...

Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...
