摘要: 南太湖主地標(biāo)集中商業(yè)為大體量超限高層商業(yè)建筑，平面呈 L 形，采用鋼筋混凝土框架(局部鋼框架)結(jié)構(gòu)體系，平面布置復(fù)雜。存在扭轉(zhuǎn)不規(guī)則、凹凸不規(guī)則、樓板不連續(xù)、局部不規(guī)則(斜柱、穿層柱、個別構(gòu)件轉(zhuǎn)換)及結(jié)構(gòu)超長等特點(diǎn)。通過多種計(jì)算軟件進(jìn)行彈性、彈塑性分析和結(jié)構(gòu)抗震性能化設(shè)計(jì)，并進(jìn)行了超長結(jié)構(gòu)的溫度應(yīng)力作用分析、商業(yè)聯(lián)橋的舒適度驗(yàn)算并采用 TMD 阻尼器對聯(lián)橋舒適度進(jìn)行控制，以及框架柱的屈曲分析。分析結(jié)果表明，主地標(biāo)集中商業(yè)結(jié)構(gòu)能達(dá)到設(shè)定的性能目標(biāo)要求，結(jié)構(gòu)各項(xiàng)指標(biāo)能較好地滿足規(guī)范的相關(guān)要求。

Abstract: The main landmark concentrates commerce of South Taihu Lake is an out-of-code high-rise commercial building，the volume of the building is enormous and the plane is L-shaped,the structural form is reinforced concrete frame and somelocal structures are steel frame. The plane layout is relatively complex,which is characterized by torsion irregular,concaveand convex irregular,floor discontinuity,local irregular ( inclined column,through column,individual componentconversion) and the structure is super long and so on. The elastic and elastic-plastic analysis,structure seismicperformance-based design,temperature stress analysis of super long structure,comfort check calculation of commercialbrace bridge,vibration reduction control analysis on the brace bridge by TMD,and buckling analysis of frame columns wereperformed by multiple calculation softwares. The analysis results show that the main landmark concentrates commerce canmeet the set performance target requirements,and the various indicators of the structure can better meet the relevantrequirements of the specification.
Keywords:out-of-code high-rise commercial building； frame structure； seismic performance-based design； temperaturestress； comfort check calculation； buckling analysis
