摘　　要： 根据层间弯剪型力学模型,运用刚度矩阵缩聚法建立总侧移刚度矩阵,采用雅可比法求解结构动力特性,选用退化双线型滞回曲线作为层间恢复力模型,建立了高层建筑结构的弹塑性地震反应时程分析的有关公式和计算程序.通过算例的计算结果对比,证明这种计算结果与其他计算结果符合较好. Using the condensation approach, the whole stiffness matrix of structural system is derived based on shear-bending storey-post mechanical model. The Jacobi method is applied to find the natural frequency and mode of vibra-tion of structure. The degenerate bilinear hysteretic loop segments are used as storey-post restoring force model. The program of the elasto-plastic earthquake response analysis of tall building structures is designed with the equations derived in this paper. The comparison of the calculating results of an example structure shows that the agreement between the results given by this paper and other methods is good.
