以高层建筑中刚臂—芯筒结构体系为分析对象，在对刚臂进行有限元分析的基础上，采用杆系一层模型进行了该体系的的弹塑性动力分析。将迁移子结构法用于高层建筑的动力分析中，并将该法和Ｗｉｌｓｏｎ－θ法结合起来求解高层建筑的非线性时程响应计算了两个工程实例，结果证明这是一种具有较好精度和行之有效的方法 Taking the rigid-arm structure of a high-rise building as the analysis object, based on the finite element analysis of the rigid arm, the elasto-plastic dynamic analysis of the system was performed using a model of the bar system. The migration substructure method was used in the dynamic analysis of high-rise buildings, and the method was combined with the Wilson-θ method to solve the nonlinear time-history response of high-rise buildings. Two engineering examples were calculated and the results proved that it was a better one. Accuracy and proven method
