摘　　要：某大型医院新建病房楼主楼采用框架-剪力墙结构体系,裙房采用框架结构,二者之间不设防震缝。由于新建病房楼结构存在扭转不规则、凹凸不规则、主楼偏心布置及立面收进等超限情况,与老病房楼之间还设置了高位架空连廊,新建病房楼属于超限复杂高层结构。首先介绍新建病房楼的工程特点、结构布置及超限情况,然后对整体结构进行了弹性分析、时程分析和Pushover分析,最后有针对性地提出了抗震措施。结果表明,新建病房楼结构达到了预期的抗震性能目标,结构设计满足规范要求。The main building of the newly-buih ward building of a large-scale hospital adopts the frame-shearwall structural system and the podium adopts frame structure, and there is no seismic joint between them. The newly-buih ward building belongs to the out-of-code and complicated high-rise structure because there are out-of-code conditions of torsion irregularity, concave-convex irregularity, eccentric arrangement of main building and vertical setback and there are also high spatial corridors connected with the old ward building. First, project characteristics, structural arrangements and out-of-code conditions of the newly-buih ward building were introduced. Then elastic analysis, time-history analysis and Pushover analysis were conducted on the whole structure. Finally, specific seismic measures were proposed. The results show that the newly-buih ward building can achieve the expected seismic performance objectives, and structural design meets the code requirements.
