摘要: 眉山 58 號地塊項目 1#塔樓采用鋼筋混凝土框架-核心筒結(jié)構(gòu)體系,結(jié)構(gòu)高度 141. 60m,為 B 級高度的超高層建筑. 為了滿足建筑功能和立面造型的需要,在結(jié)構(gòu)相應(yīng)位置設(shè)置了穿層柱、斜柱和牛腿柱. 通過 SATWE 和MIDAS Building 兩種軟件對結(jié)構(gòu)進行了多遇地震下的反應(yīng)譜分析,并借助 SATWE 軟件進行彈性時程分析作為補充驗算. 采用 SATWE 軟件對結(jié)構(gòu)進行了等效彈性分析,保證主要構(gòu)件滿足設(shè)防地震和罕遇地震作用下的抗震性能化設(shè)計目標(biāo). 運用 SAUSAGE 軟件對結(jié)構(gòu)進行了罕遇地震下的動力彈塑性時程分析,以保證結(jié)構(gòu)“大震不倒”.基于 MIDAS Gen 和 ABAQUS 等軟件對穿層柱、斜柱和牛腿柱進行了專項分析,確保了重要部位的安全性. 結(jié)果表明,結(jié)構(gòu)具有良好的抗震性能,能達到預(yù)設(shè)的 C 級抗震性能目標(biāo).

Abstract: Tower 1 of Meishan 58 Plot project adopts reinforced concrete frame-core tube structure system, with a structuralheight of 141. 60m, which is a super high-rise building with B-level height. In order to meet the needs of building functionand facade modeling, some cross-story columns, an inclined column and a cow-leg pillar were set in the correspondingposition of the structure. By using SATWE and MIDAS Building software, the response spectrum analysis of the structureunder frequent earthquakes was carried out, and the elastic time history analysis was taken as a supplementary check byusing SATWE software. The equivalent elastic analysis of the structure was carried out by SATWE software to ensure theperformance-based seismic design objectives of the main components under fortification and rare earthquakes. The dynamicelastic-plastic time-history analysis of the structure under rare earthquakes was carried out by using SAUSAGE software,making sure that the structure won’t collapse under rare earthquakes. Based on MIDAS Gen, ABAQUS and other software,special analysis of the cross-story columns, the inclined column and the cow-leg pillar were taken to ensure the safety ofimportant parts. The results show that the structure has good seismic performance and can reach the preset C class seismicperformance target.
Keywords:super high-rise building; frame-core tube structure; performance-based seismic design; dynamic elastic-plastictime-history analysis; special analysis
