摘　　要：对天津某高烈度区高层住宅进行结构超限情况判断,发现结构存在高度超限、扭转不规则、凹凸不规则等多项不规则项。针对结构的不规则项,设定合理的结构抗震性能目标,通过不同的结构分析软件研究结构在多遇地震、设防地震、罕遇地震的受力性能,采用弹性时程分析、静力弹塑性(Pushover)分析,深入探讨结构在地震中的反应,找出结构在地震反应中的薄弱位置,对这些薄弱位置进行相应的加强,使结构设计满足预定的性能目标。The paper evaluates the structural over-limit situation of a high-rise residential building in a high-seismic-intensity area in Tianjin.Multiple irregularities were found,including height over-limit,torsional irregularity and concave-convex irregularity.To tackle these issues,reasonable seismic performance objectives were set,and the structure's force performance during frequent,design,and rare earthquakes was investigated using various structural analysis software.Elastic time history analysis and static elastic-plastic analysis were used to further analyze the seismic response of the structure and to identify the weak points of the structure.The weak points were strengthened accordingly to satisfy the predetermined performance goals.
