［摘要］蘇州綠地中央廣場綜合樓建筑總高度為243-4m，地上58層，地下3層，采用鋼筋混凝土框架-核心筒結(jié)構(gòu)體系，結(jié)構(gòu)平面和豎向均存在不規(guī)則項，屬于超B級超限高層建筑工程。首先介紹了塔樓結(jié)構(gòu)的方案比選和最終結(jié)構(gòu)布置，然后根據(jù)設(shè)定的抗震性能目標(biāo)，對主體結(jié)構(gòu)進(jìn)行了小震、中震和大震性能計算，并對大開洞樓板進(jìn)行了樓板受力性能分析。此外，通過Pushover分析獲得了結(jié)構(gòu)構(gòu)件屈服順序；通過彈塑性時程分析獲得了結(jié)構(gòu)在大震作用下的殘余變形。根據(jù)分析結(jié)果對薄弱部位采取加強(qiáng)措施，確保結(jié)構(gòu)在滿足建筑功能、經(jīng)濟(jì)合理的條件下具有較好的抗震和抗風(fēng)性能。

Abstract:The complex building of Suzhou Greenland Central Plaza has 58 stories above ground and 3 stories underground. The building height is 243-4m. Reinforced concrete frame-core tube structure system is adopted. There are irregular terms in the plane and vertical direction of the structure, which belongs to the super B grade out-of-code high-rise building engineering. The comparison and selection of the tower structure and the final structural arrangement were introduced firstly. Then performance calculation of the main structure under frequent earthquake, medium earthquake and rare earthquake were carried out based on the seismic performance targets. And mechanical behavior analysis on floor with big opening hole was carried out. In addition, the yield order of structural members was obtained by Pushover analysis, and the residual deformation of structure subjected to rare earthquake was obtained by elastic-plastic time history analysis. According to the analysis results, measures were taken to strengthen the weak parts to ensure the high performance under earthquake and wind while satisfying the requirements of architectural functions and economic rationality.
Keywords:out\|of\|code high-rise structure; performance-based seismic design; Pushover analysis; elastic-plastic time history analysis; floor mechanical behavior analysis
