Abstract

This paper presents a nonlinear analysis of reinforced concrete structures. Various yield
surfaces of concrete are reviewed in the beginning and then a recently proposed yield surface for concrete is
introduced. The yield surface considers the behavior of concrete in a three-dimensional stress state. Based
on the yield surface, a nonlinear nite element formulation is provided to facilitate a three-dimensional
analysis of reinforced concrete structures. An eight-node brick element is used in the analysis. Several
numerical examples are given to show the ability of the yield surface in solving nonlinear reinforced
concrete problems.
