Abstract

Compressive Membrane Action (CMA), also called Arching Action, increases both bending and punching capacity of reinforced concrete (RC) structures. In the paper a non-linear finite element (NLFE) approach which adopts multi-layered shell modelling of RC slabs is presented. Post-processing of NLFEA results is presented which exploits the Critical Shear Crack Theory (CSCT) to evaluate the punching shear resistance of shell elements. The numerical procedure is adopted to evaluate CMA effects on the punching shear resistance of the Corick bridge deck subjected to concentrated loads. Finally the design punching shear resistances evaluated with the presented procedure are compared with the analytical values calculated with the British Code BD81/02.
