| 摘 要： | 基于ANSYS有限元分析软件,建立了两跨钢-混组合梁的非线性分析模型,利用该模型,对钢-混连续梁的极限荷载和挠度进行了仿真计算,将计算结果与采集的试验数据对比,验证了该模型的有效性.在连续组合梁塑性极限分析的基础上,推导了两跨连续组合梁极限状态所需的调幅系数,并探讨了结构所能提供的调幅能力以及调幅系数的确定方法.

| Abstract: | By the FEA of ANSYS, a two-span continuous steel-concrete composite beam model for nonlinear analyses is established in the paper, with the amount of deflection and limited loads of the steel-concrete composite beam simulated and calculated. The calculated results are compared with the collected test results so as to verify the effectiveness of the model. On the basis of the limits analysis, the required reducing coefficient for moment redistribution to enable the full plastic mechanism for continuous composite beams is derived, and the available moment redistribution capacity of the beams and the method to evaluate the available moment redistribution capacity are also dealt with in the paper. |
