混凝土系杆拱桥温度应力有限元分析

2008-06-28

摘  要：以某混凝土刚架系杆拱桥为原型，借助ANSYS软件建立平面有限元模型，计算拱肋结构各控制截面在温度荷载作用下的内力与应力值，并通过改变矢跨比，将不同情况下的计算结果进行对比，并对结果进行分析。

Abstract: This paper calculates stress and internal force of the arch rib section in CFST tied arch bridge under the temperature stimulates by finite element method (FEM).And this paper analyses the contrast of different results base on different design parameters which are caused by changing ratio of rise to span and coefficient of arch axis.

Keywords: CFST tied arch bridge; temperature stress; FEM
