Nonlinearity Analysis of Reinforced Concrete Based on ABAQUS

G Zhang, R China

Abstract

Concrete constitutive relations, failure creiterions and the tension stiffing in the large element software ABAQUS are introduced thoroughly.The factors which affect converge and accuracy in the nonlinearity analysis are also recommended.Finally,take a freely supported beam as an analysis example,proceeded a finite element analysis using ABAQUS,and compare the calculation values with the theory values.The result indicates that the calculation values in ABAQUS approach the theory values.It proves that the method may be used to simulate the mechanic capability analysis of reinforced concrete structure,and have a perfect accuracy.
