［摘要］ABAQUS软件缺少能良好应用于三维梁单元动力弹塑性分析的混凝土材料模型。基于Scott-Kent-Park混凝土模型二次开发了适用于梁单元的混凝土材料子程序，并对框架柱、剪力墙构件的低周反复试验及框剪结构振动台试验进行了模拟对比分析。结果表明，开发的混凝土材料子程序应用于三维梁单元弹塑性动力分析中具有良好的精度和收敛性，是对ABAQUS中的混凝土材料模型的有效扩充，可供三维结构动力时程分析参考。

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
