Abstract

To study the influence of composite action of floor slab on aseismic behavior of steel-concrete mixed frame structures, models of composite beam-concrete-filled square steel tubular columns frame structure (CB-CFST) and steel beam- concrete-filled square steel tubular columns frame structure (SB-CFST) with and without considering the composite action of floor slab were constructed. Influence analysis of elastic and inelastic aseismic behavior was conducted. The influence of the composite action of floor slab on mechanical behavior, deformation and damage state of structures were investigated. The results showed that the upper column design internal force of steel beam frames would be smaller than that of composite beam frames, which would make the structure design unsafe. And considering the composite action of floor slab, the displacement response of CB-CFST was smaller than that of SB-CFST in the mass. Furthermore, real damage state couldn’t be reflected without considering the composite action of floor slab
