摘要
根据欧洲规范EC4中的方法对节点的初始刚度进行计算并提出修正的承载力简化计算模型,给出一个三参数幂函数模型对齐平端板组合节点的连接特性进行模拟。提出用拟合曲线与试验曲线耗能能力差值最小的方法来判定M-曲线拟合的程度,进而确定适用模型的形状参数n。并用有限元结果进行验证。
The stiffness of connection was calculated by using the methods in EC4 and the simplified model for calculating the resistance was amended in this paper. The ultimate moment resistance of composite flush end-plate joint was calculated. The model of linear three-parameter power was built and the behaviors of composite flush end-plate joint were simulated. A new method of determining the ＂n＂ in the calculating model was established. The Veracity and precision of the methods were provided by comparing with the results of the finite element models.
