摘　　要：对某地铁控制中心进行结构超限情况判断,结构存在扭转不规则、楼板不连续、凹凸不规则、尺寸突变、构件间断等多项不规则项。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,通过弹性时程分析和动力弹塑性分析进一步分析结构的地震反应,发现结构的薄弱位置,对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。Structural overlimit analysis was conducted on a subway control center,revealing the existence of several irregularities such as torsion irregularity,unevenness,discontinuity of floor slabs,abrupt changes in dimension,and component disconnection.Based on these irregularities,rational seismic performance objectives were established for the structure.Through the use of various structural analysis software,the structural behavior was studied under earthquake scenarios,including frequent earthquakes,design earthquakes,and rare earthquakes.Elastic time-history analysis and dynamic elastic-plastic analysis were used to further investigate the structural seismic response.Weak positions in the structure were identified,and appropriate strengthening measures were implemented to satisfy the specified performance objectives.
