摘要
提出了部分剪力连接钢 -混凝土组合梁非线性有限元分析的简化模型 ,该模型同时考虑了钢、混凝土材料的非线性本构关系和剪力连接件的滑移非线性对组合梁刚度和强度的影响 ,推导了考虑滑移的剪力连接件单元刚度矩阵。利用该模型计算了连续组合梁的极限荷载、挠度、应力以及滑移 ,与已有的理论计算结果和实验结果吻合 ,证明本方法分析钢
A simplified finite element model for analysis of the steel-concrete composite beams with incomplete interaction is presented. The effects of material nonlinearities of concrete, steel and shear connectors on the stiffness and strength were considered in the model. Based on slip, a shear connector element stiffness matrix was derived. The ultimate load, deflection, stress and slip of a continuous composite beam were calculated. Compared the present results with the experimental and other numerical method results proved that the model provided is correct and convenient for the analysis of the steel-concrete composite beam in the practice.
