［摘要］保山数据中心机楼为多层建筑，且结构无对抗震不利的平面与竖向不规则。由于本工程地处高烈度区，且建筑物属于重点设防类，结构自重较一般工程大。因此工程师在设计过程中本着尽量优化结构受力的初衷，对结构方案进行了多方面的尝试。设计过程中通过五种结构方案的对比，最终选定强边框+BRB支撑-普通内框架的结构体系。并针对确定后的结构体系分析其在小震、中震、大震下的结构受力特点和受力的合理性。最终说明了在地震作用力较大的地区，类似建筑选用本结构形式的优越性。

Abstract: The building of Baoshan data center is a multi-storey building, there is no plane irregularity and vertical irregularity which can cause bad effects on the seismic. However, this building is a key fortification building with larger load than general projects, and located in the high intensity zone. Engineers have attempted variety of structural schemes for the purpose of optimizing the structure stress. Eventually, enhance surrounding frame+BBR support+common inner-frame is chosen for this project after comparing with the other four different kinds of structural proposals. The stress characteristic and stress rationality were analyzed under the frequent earthquake, moderate earthquake and rare earthquake. In the end, the results show that the structural system has more advantages, when it is used for the building with large weight in the high intensity zone. 

Keywords: enhance surrounding frame-common inner-frame structure; isolated from the earthquake and reduce the earthquake design; performance design; BRB buckling constraint support; substructure
