Nonlinear Analysis of Reinforced Concrete Beam Bending Damage Experimentation Based On ABAQUS

摘要: 本文采用ABAQUS有限元分析软件对钢筋混凝土梁进行非线性分析，针对小梁试验中的一根简支梁进行有限元分析，采用混凝土损伤塑性模型，对比了试验分析与使用ABAQUS分析的计算结果，探讨了结果产生差异的原因，为进一步进行ABAQUS钢筋混凝土结构有限元分析提供了参考。

Abstract: Based on the the finite element analysis software ABAQUS, the nonlinear analysis of a reinforced concrete beam was carried out.In this simple beam analysis, the concrete damage plasticity model in ABAQUS has been introduced thoroughly.Finally, the results of the experimentation and the ABAQUS analysis were compared in a diagram, accordingly reasons of the result difference between the two methods were discussed about, which can be a useful reference for the further study of the finite element analysis on ABAQUS.
