Paper Title:
Theoretical and Numerical Analysis on Membrane Effects of RC Slabs
  Abstract

When a RC structure is laterally restrained, the load resistance is enhanced due to the membrane effects. A simplified membrane action theory was proposed by modifying the Maximum Membrane Force Design Method (MMFM) to predict the resistance-deflection curves of restrained slab RC structures, in which the total strain plastic theory and strain rate plastic theory were combined and a serial of explicit formulae were derived. A better agreement was observed between the test data and the analytical results predicted by the proposed theoretical method, comparing with MMFM and numerical results conducted by ABAQUS. It is demonstrated that the proposed theory is validated and the steel bar at compressive zone has definite influence on the load carrying capacity, and cannot be neglected in the case of high compressive reinforcement ratio.
