Effect of Combined Beam Slab Interactive Resisting Mechanism for Progressive Collapse

Abstract

In reinforced concrete structures slab, beam and column plays an important role in load transfer mechanism. When a column fails due to earthquake or attack, progressive collapse may occur. There is a need to study and understand the performance of the RC framed structure under progressive collapse to design a better structure. This study investigates the effect of combined Beam-Slab interactive resisting mechanism against progressive collapse using finite element software. Linear static analysis was used to study the progressive collapse of the RC framed structure. The models of symmetrical regular building with bare frame, frame with slab and frame slab with infill were studied. The parameters like load carrying capacity, energy dissipation factor and stiffness degradation were analysed. The analysis results showed that frame slab with infill showed better resistance during progressive collapse.
