| 摘 要： | 根据钢-混凝土组合梁的特点，介绍了钢一混凝土组合梁受力时采用有限元分析的原理，推导了剪力连接件的单元刚度矩阵表达式，建立了连接件的非线性有限元模型．采用大型有限元软件ANSYS作为仿真分析工具，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．分析结果可以指导实际工程中对组合梁设计的连接程度的选择．

| Abstract: | On the basis of the characteristics of steel-concrete composite beams,the authors introduce the principle of the finite element analysis of stressed steel-concrete composite beams,develop the matrix representation of the unit rigidity of the shearing connecting pieces,and establish the nonlinear finite element model of the connecting pieces.With the large-scale software of finite element ANSYS as the means of simulation analysis,they analyze the stresses,deformations and glides of the simple steel-concrete composite beams under different shearing linkage degrees,supposing the loads are uniformly distributed.The results might be helpful for the determination of a sound connecting way of the beam in practice. |
