［摘要］保山數(shù)據(jù)中心機(jī)樓為多層建筑，且結(jié)構(gòu)無對抗震不利的平面與豎向不規(guī)則。由于本工程地處高烈度區(qū)，且建筑物屬于重點(diǎn)設(shè)防類，結(jié)構(gòu)自重較一般工程大。因此工程師在設(shè)計(jì)過程中本著盡量優(yōu)化結(jié)構(gòu)受力的初衷，對結(jié)構(gòu)方案進(jìn)行了多方面的嘗試。設(shè)計(jì)過程中通過五種結(jié)構(gòu)方案的對比，最終選定強(qiáng)邊框+BRB支撐-普通內(nèi)框架的結(jié)構(gòu)體系。并針對確定后的結(jié)構(gòu)體系分析其在小震、中震、大震下的結(jié)構(gòu)受力特點(diǎn)和受力的合理性。最終說明了在地震作用力較大的地區(qū)，類似建筑選用本結(jié)構(gòu)形式的優(yōu)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
