Progressive collapse simulation of the steel-concrete composite floor system considering ductile fracture of steel

The prediction of the structural behavior under the progressive collapse scenario has received growing attentions in recent years. The failure of the bolted shear tab connection is usually dominated by the shear fracture. However, few researchers have considered the effect of the shear fracture in the progressive collapse simulation. This research develops a practical modeling routine to upscale the material shear fracture model in the collapse...
