MATERIAL NONLINEAR ANALYSIS OF REINFORCED CONCRETE SLABS CONSIDERING THE EFFECT OF BOND-SLIP OF REINFORCEMENT

Abstract

This paper deals with the material nonlinear analysis of reinforced concrete slabs considering the effect of bond slip of reinforcement. Only a small number of studies have been reported in the literature that approximately consider the effect of reinforcement bond slip in two-way reinforced concrete slabs, and almost no cases are found in which material nonlinear analysis is used to rigorously consider the effect. In this paper a potential energy functional is first derived, and then a finite element formulation of the problem is implemented. In order to verify the analytical method five numerical examples are given and the results compared with experimental results.
