Nonlinear Analysis on Reinforced Concrete Based on ABAQUS and ANSYS

The paper makes an introduction to the basic theory of finite element software ABAQUS and ANSYS in nonlinear analysis of reinforced concrete,and emphases are put on the material constitutive models and the parameter determination methods.Finally,ABAQUS and ANSYS are used for analyzing a simple reinforced concrete support beam,whose results are compared with the calculation values from code formula,so as to obtain the causes of errors and the applicable conditions.The results show that the nonlinear analysis of reinforced concrete by taking use of ABAQUS and ANSYS has preferable accuracy.
