摘　　要：介绍了静力弹塑性分析的基本原理和主要计算步骤,在此基础上提出了高层建筑结构中能力谱的修正方法,并进一步讨论了侧向荷载分布形式对结构能力谱的影响,在大震作用下角边柱出现拉力,附加阻尼对结构需求谱的折减等问题。对某超B级高层建筑结构进行静力弹塑性分析,对其抗震性能做出了评估。The principle and main calculation steps of static nonlinear analysis are introduced. In order to use the method in tall buildings, the improved method for capacity spectrum is put forward. Some problems such as the influence of lateral load mode on capacity spectrum, the pull force of column under rare earthquake action, the decrease of demand spectrum on aceount of additional damping, are discussed. The static nonlinear analysis is applied to a super high rise building and its seismic performance is evaluated.
