［摘要］于家堡寶龍國際中心3#樓主體結(jié)構(gòu)采用鋼管混凝土框架-鋼筋混凝土核心筒-伸臂桁架結(jié)構(gòu)體系，存在多項(xiàng)超限。采用SATWE及MIDAS Gen兩種有限元軟件對(duì)結(jié)構(gòu)進(jìn)行基本靜動(dòng)力性能分析，各項(xiàng)指標(biāo)均滿足相關(guān)規(guī)范要求。采用7條時(shí)程曲線對(duì)結(jié)構(gòu)進(jìn)行彈性時(shí)程分析，對(duì)振型分解反應(yīng)譜法進(jìn)行補(bǔ)充校核。結(jié)果表明，彈性時(shí)程分析結(jié)果與振型分解反應(yīng)譜法結(jié)果基本一致。采用3條時(shí)程曲線對(duì)結(jié)構(gòu)進(jìn)行彈塑性時(shí)程分析，結(jié)構(gòu)各項(xiàng)指標(biāo)均滿足規(guī)范要求，表明結(jié)構(gòu)可以滿足“大震不倒”的抗震性能目標(biāo)。采用MIDAS Gen軟件對(duì)結(jié)構(gòu)進(jìn)行施工過程模擬，主要分析結(jié)構(gòu)的豎向變形特性。在變形的各個(gè)組成成分中，結(jié)構(gòu)自重以及外荷載引起的變形起主要作用，核心筒與外部框架柱最大豎向變形差為3-14mm。

Abstract:The main structure of Powerlong International Center 3# building in Yujiapu adopts the form of concrete-filled steel tubular column frame, reinforced concrete corewall and outriggers structure, and there are a number of out-of-code items. Two kinds of finite element software SATWE and MIDAS Gen were used to analyze the static and dynamic performance of the structure, and all indexes meet the requirements of the relevant specifications. Seven time-history curves were used to carry out the elastic time-history analysis, which was the supplement and check of the mode-superposition response spectrum method. The calculation results indicate that the elastic time-history analysis results were almost the same as the results of mode-superposition response spectrum method. Three timehistory curves were used to carry out the elastic-plastic time-history analysis of the structure and all indicators meet the specification requirements, so the structure could satisfy the seismic fortification target of “no collapsing under the rare earthquake”. MIDAS Gen software was used to simulate the construction process, and the vertical deformation characteristics were mainly analyzed. In the components of deformation, the deadweight of the structure and the external load had main effects. The maximum vertical deformation difference between the corewall and the outer frame column was 3-14mm.

Keywords:basic performance analysis; dynamic time-history analysis; construction process simulation; deformation characteristic analysis
