摘要: 高层建筑结构在地震作用下的动响应分析一直是土木工程结构设计中的难点问题.采用同时具有高精度和长时间数值稳定性的辛精细积分方法开展了高层建筑结构的地震时程分析,得到了结构弹性/弹塑性时程分析结果,并将分析结果与当前流行的商业软件分析结果进行对比,验证了采用辛精细积分方法进行高层建筑结构地震时程分析的可行性与有效性.Abstract: The response analysis of tall buildings under earthquake action is a difficult task in civil engineering design. With the symplectic precise integration method, which has advantages of high precision of the precise integration method and excellent long-time numerical stability of the symplectic method, the seismic response analysis of a tall building was performed and the elastic/elasto-plastic time-history results of the structure were obtained. Comparison of the numerical results between the symplectic precise integration method and the EPDA software shows the feasibility and the effectiveness of the symplectic precise integration method for seismic response analysis of tall buildings.
