Abstract

Abstract: In this paper, the constitutive models, as well as the properties of their element and the models of FEA are discussed. No nlinear analysis for reinfor ced concrete rigid-frame arch bridge containing carried out by using the lar gegeneral structural analysis softw are ANSYS. Geometric nonlinearity and material nonlinearity of members are also considered. The effects of different load dist ributions on the ultimate load-carrying capacity of the bridge are investigated.

Key words: reinforced concrete, rigid-frame arch bridge, geometric nonlinearity , material nonlinearity

摘要： 运用ANSYS进行钢筋砼刚架拱桥的非线性分析,探讨了单元特性以及有限元模型的建立,完成非线性分析.分析过程中综合考虑了结构几何非线性和材料非线性对极限承载力的影响.最后,探讨了不同荷载分布方式对结构极限承载力的影响.
