摘　　要：呼市百货公司新城商业办公综合楼为位于高烈度区的续建项目。原结构为混凝土-框架剪力墙结构,施工到6层后进行了续建,续建部分采用矩形钢管混凝土框架柱-钢支撑结构体系,并按照现行规范进行设计。介绍了原建和续建部分的结构体系和关键部位的加强措施,框架柱节点在过渡区的细部构造,补充了罕遇地震弹塑性时程分析,结果表明,结构满足"大震不倒"的设防目标。在较为经济、合理的条件下,项目各关键构件满足所设定的抗震性能目标,结构具有良好的抗震性能。The new commercial office complex building of Hohhot Department Store is a continued construction building located in high seismic intensity region. The original structure is concrete frame shear wall structure. Continued construction is conducted after the construction completion of 6th floor. The continued construction part adopts rectangle concrete filled steel tube frame column and steel support structural system,and the structure is designed according to current codes. The structural systems of the original part and the continued construction part as well as strengthening measures in key parts and detailed construction of column in transition part. Elastic-plastic time-history analysis under rare earthquake was supplemented. Results show that the structure meets fortification objective of ＂not collapsing under rare earthquake＂. Under the economic and reasonable condition,key components of the project meet the proposed seismic performance objective,so the structure has good seismic performance.
