摘要
介绍钢-混凝土组合梁的有限元分析原理,建立了剪力连接件的单元刚度矩阵表达式,提出了连接件的非线性有限元模型。采用大型有限元软件ANSYS对均布荷载作用下的钢-混凝土简支组合梁在不同剪力连接程度下的应力、变形和滑移进行了分析。分析结果可用于组合梁实践应用中的连接程度优化选择。
This paper presents the theory of finite element method for steel-concrete composite beams, set the element stiffness matrix of the shear connector, and established nonlinear finite element model. It investigated the stresses, deflections and slips of steel-concrete composite simply supported beams with different shear connection degrees under uniform loads by ANSYS software. The results may be used in the design＇of steel-concrete composite simply supported beams to select an optimal shear connection degree.
