Abstract:In FEM software ABAQUS, there is no concrete material model that can be well applied to the dynamic elasto-plastic analysis of three-dimensional beam element. Based on Scott-Kent-Park model, user-defined-material-subroutines for the three-dimensional beam element were developed to analyze three-dimensional reinforced concrete beam-column component. Then simulations for the horizontal cyclic loading test of RC frame column and shear wall component, and the shaking table test of frame-shear wall structure were carried out for calibrating the developed material model. The results indicate that the user-defined-materialsubroutines have good accuracy and convergence, and the concrete material models of ABAQUS are effectively expanded. It provides reference to dynamic analysis of 3D structure.

Keywords:elasto-plastic analysis; concrete material model; reinforced concrete structure; ABAQUS
