Abstract：An effective new method was presented to calculate concrete damage parameters of ABAQUS. Three reinforced concrete columns under reversed cyclic loading were analyzed using concrete damaged plasticity model. Effects of several different methods for calculating damage parameters on the numerical results were investigated in this paper. The effectiveness of the present method was verified by three numerical examples.

Keywords: concrete structures; reversed cyclic loading; ABAQUS; damage parameter; numerical analysis.
