湖北省电力公司调度通信楼结构设计

Structural design of communication building of Hubei Electric Power Company

湖北省电力公司调度通信楼属于具有复杂平、立面的超限高层建筑结构。介绍了该工程抗震性能设计、楼板弹性应力分析、屋顶大跨度连廊的结构形式比选、连廊结构舒适度分析等结构设计的关键内容。采用SATWE和MIDAS软件对整体结构进行多遇地震及风荷载作用下的弹性分析及弹性动力时程分析,达到了结构构件的抗震性能设计目标。弹塑性分析也表明结构能够满足罕遇地震作用下的受力要求。

The communication building of Hubei Electric Power Company(HBEPC) is an ultra-limit high-rise building with complex plane and elevation features.The design of the seismic performance of the structure,elastic stress analysis of floors,comparison and selection of structural form of the long span corridor between the two ends of the L-shaped roof floor,comfort analysis of the corridor and other important contents of structural design were introduced.Elastic analysis and elastic dynamic time history analysis under frequently occurred earthquakes and wind load had been analyzed by using the software of SATWE and MIDAS respectively and static elasto-plastic analysis(Pushover) had also been carried out by using the software of MIDAS/Gen.All the results show that all the calculation indexes of the project are in accordance with the requirements of the specification,and the predetermined seismic performance targets are met.
