COMPRESSIVE MEMBRANE ACTIONS IN EDGE-RESTRAINED REINFORCED CONCRETE SLABS : Comparison of experiments with material-nonlinear solutions with stress reduction due to concrete crushing considered

Abstract

Material nonlinear analysis for reinforced concrete slabs with restrained edges is made using the finite element method with necessary formulations incorporated in it for the movement of their middle surface owing to cracking and other related effects, in both cases of taking and not taking account of compressive membrane actions. The results for the concerned load-bearing behaviors are compared with experimental measurements, with the adopted procedures shown to be valid to a resonable extent.
