［摘要］柳州三胞國際廣場2#樓屬于超A級(jí)高度高層建筑，為框架-核心筒結(jié)構(gòu)體系。采用SATWE和PMSAP兩種軟件進(jìn)行了彈性計(jì)算，并對(duì)核心筒內(nèi)剪力墻布置進(jìn)行了經(jīng)濟(jì)性比較分析。計(jì)算結(jié)果表明，結(jié)構(gòu)的周期比、層間位移角等指標(biāo)均滿足規(guī)范要求。采用性能化設(shè)計(jì)方法保證了主要構(gòu)件在中震和大震作用下的性能要求。采用SAUSAGE軟件進(jìn)行動(dòng)力彈塑性分析，保證了結(jié)構(gòu)大震不倒。通過概念設(shè)計(jì)和計(jì)算分析，對(duì)關(guān)鍵構(gòu)件進(jìn)行了適當(dāng)加強(qiáng)。通過以上措施，結(jié)構(gòu)抗震性能達(dá)到既定目標(biāo)，結(jié)構(gòu)安全可靠。

Abstract:No.2 tower of Liuzhou Sanpower International Plaza is a high-rise building exceeding A-level height requirement of codes. It adopts frame-corewall structural system. Programs of SATWE and PMSAP were used to conduct the elastic calculation under the frequent earthquakes, and economy caused by different layout of shear wall in the corewall were compared. Results show that, period ratio and interlayer displacement angle of the structure meet specification requirements. Performance-based design method was adopted to ensure the performance requirements of main components under fortification and rare earthquakes. SAUSAGE software was used to conduct the dynamic elastic-plastic analysis to ensure that the structure would not collapse under rare earthquake. Based on the concept design and calculation results, the key components were properly strengthened. Through above measures, the structural seismic performance can reach the appointed objective, and the structure is secure and reliable.

Keywords:out-of-code high-rise building; frame-corewall; elastic time-history analysis;performance-based seismic design; dynamic elastic-plastic analysis
