Abstract

The progressive collapse behaviour of reinforced concrete (RC) structures requires consideration of material and geometric non-linearity, concrete crushing and rebar fracture. Compressive arch action (CAA) and catenary action (CTA) are the main resisting mechanisms against progressive collapse following a column loss. Hence, many studies have concentrated on the development of CAA and CTA in RC beams, but without considering the effect of bar fracture and the reduction in beam effective depth due to concrete crushing. Taking these additional factors into account, an analytical model to predict the structural behaviour of RC beams under a column removal scenario was developed. The proposed model was evaluated and validated with the available experimental results. The evaluation and validation indicate that the proposed model can provide a reliable assessment of RC beam capacity against progressive collapse.
