摘要: 溫州國(guó)鴻中心超高層塔樓地上 71 層、地下 3 層,建筑高度為 356m,采用鋼管混凝土疊合柱-鋼梁-鋼筋混凝土核心筒混合結(jié)構(gòu)體系。 為了提高整體結(jié)構(gòu)剛度,通過(guò)比選結(jié)構(gòu)加強(qiáng)層設(shè)置方案,確定了加強(qiáng)層數(shù)量、伸臂桁架及腰桁架的設(shè)置方案。 采用基于性能的抗震設(shè)計(jì)方法,針對(duì)不同超限情況采取了相應(yīng)的技術(shù)措施。 對(duì)結(jié)構(gòu)進(jìn)行了彈性和彈塑性時(shí)程分析,結(jié)果表明,結(jié)構(gòu)可滿足預(yù)設(shè)的性能目標(biāo)。 最后介紹了考慮混凝土徐變收縮的施工模擬分析。

Abstract: The super high-rise tower in Wenzhou Guohong Center has 71 floors overground and 3 floors underground withbuilding height of 356m. The building adopts hybrid structure system with steel tube-reinforced concrete column-steelbeam-reinforcement concrete core tube. Through comparison and selection of structural reinforcement layer setting plans,the number of reinforcement layers, the setting plan of outrigger truss and waist truss were determined to improve the overallstructural rigidity. Aims at different overrun situations, technical measures based on performance-based seismic designmethods were adopted. The elastic and elastic-plastic time-history analysis of the structure were executed, the results showthat the structure can fulfill expected seismic performance targets. Finally, construction simulation analysis consideringconcrete creep and shrinkage was introduced.

Keywords:super high-rise structure; steel tube-reinforced concrete column; reinforcement layer; construction simulationanalysis
