某双塔连体高层结构抗震性能分析

Seismic analysis of a tall building connected with twin towers

石家庄市某办公大楼采用双塔连体结构体系,属于特别不规则的高层建筑。通过振型分解反应谱法和弹性时程分析法对该结构的抗震性能进行分析,并在设防烈度和罕遇地震下按照C级性能目标对部分连体楼板进行应力分析,针对连接体薄弱部位采取一定的加强措施以保证结构的安全。

An office building in Shijiazhuang connected with twin towers is a special irregular high-rise building. Seismic behavior of this building is analyzed by mode-superposition response spectrum method and elastic time-history analysis. In order to ensure the safety of the building,stress analysis of the connective floor is studied under the fortification intensity earthquake and rare earthquake according to C-level performance objective. By the results,measures can be taken to strengthen the weak part.
