Anti-blast properties of RC superimposed slab shear wall

Abstract

In order to analyze the anti-blast properties of the RC superimposed slab's shear wall, comparative experimental studies of two RC superimposed slab shear walls and two in-situ cast shear walls under explosion were conducted. The structural failure feature, deformation capability, bearing capacity and crack distribution pattern were analyzed systematically. The result shows that the failure mode of the RC superimposed slab shear wall is similar to that of the in-situ cast shear wall. The stiffness of two kinds of specimen are basically identical within the elastic stage. But the post-cracking stiffness' descending speed of the in-situ cast shear wall is greater than that of the RC superimposed slab shear wall. The RC superimposed slab effectively restrained the crack extension and there were no shear failure throughout the loading procedure, which proves its high integrity. The blasting-resistance performance of the RC superimposed slab shear wall is superior to that of the in-situ cast shear wall.
