The Experimental Research of New Lightweight Steel Composite Slab

Abstract:

The new composite sandwich slab of the cold formed thin-walled steel and lightweight aggregate concrete is studied. The composite sandwich slab is a skeleton of cold formed thin-walled steel, cast-in-situ lightweight aggregate concrete, built-in benzene board as a sandwich layer. The composite sandwich slab has a light weight, seismic performance is good, and construction period is short of advantage, can effectively solve poor shortcomings of the steel structure fireproofing performance and corrosion resistance, and can effectively improve the whole and local stability of the steel structure. The composite sandwich slab bearing capacity of the cold formed thin-walled steel and lightweight aggregate concrete is analyzed using simple plastic theory. The deflection to consider interface slip of the composite slab is computed. The composite sandwich slab is tested statically; the failure mechanism of the slab is analyzed. The load-deflection curve, load-strain curve are obtained. The sandwich rate of the slab on the influence of the bearing capacity is analyzed using the finite element method, and theoretical with experimental results comparatively analyzed.
