摘　　要：石家庄之门为双塔高层混凝土框架剪力墙结构,该结构顶部3层通过钢结构连接体将2个塔楼刚性连接,为大跨连体超限高层结构。设计中对结构的薄弱位置采取了相应的抗震措施予以加强。运用多种空间有限元结构分析软件,对结构进行多遇地震下振型分解反应谱法计算分析、弹性时程分析和罕遇地震下的静力弹塑性分析,该工程结构主要设计指标均满足规范要求,混凝土结构主体及钢结构连接体承载力和延性较好。The project of the door of Shijiazhuang is a high-rise frame-shearwall structure with two towers. The top three layers of the two towers are rigid connected by the steel connector. The structure is a large- span conjoined transfinite high-rise structure. The weak position of structural aseismic measures should be taken to strengthen in the design. By using a variety of spatial finite element analysis software under the conditions of multi earthquake, the elastic history analysis and Pushover analysis showed that the main in- dexes cart meet the requirement of the codes, the capacity and ductility of the main structure and the steel truss connector are well.
