基于ANSYS的钢筋混凝土梁非线性分析

Nonlinear finite element analysis base on ANSYS of RC beam

介绍了基于ANSYS软件钢筋混凝土结构非线性有限元分析的技术要点以及分析中需要注意的问题,用ANSYS对一根钢筋混凝土简支梁进行非线性全过程分析,研究钢筋混凝土梁荷载与跨中挠度关系、刚度变化规律、破坏特征、裂缝发展形态以及钢筋、混凝土应力发展过程,并与理论计算结果进行了对比分析。

In this paper,a series of key techniques and questions on nonlinear finite element analysis of RC beam using ANSYS software are discussed.Nonlinear finite element analysis is carried on a RC beam using ANSYS.The relationship of load and middle span deflection,the development of RC beam stiffness,the failure modes,the crack propagation,stress development of reinforcement bars and concrete in the RC beam are analyzed.And the comparative analysis is made with theoretical calculation.
