摘要: 白鷺灣濕地段 L5 林盤建筑采用帶弧形懸挑空腹桁架的鋼框架-支撐結(jié)構(gòu). 通過(guò)弧形空腹桁架受力特點(diǎn)及三種桁架體系的對(duì)比分析,確定了內(nèi)、外環(huán)弧形空腹桁架間設(shè)置豎向人字形支撐的懸挑桁架結(jié)構(gòu)形式. 多遇地震下的彈性時(shí)程分析得到的樓層位移、最大層間位移角及樓層剪力均與反應(yīng)譜分析的結(jié)果較吻合,驗(yàn)證了采用反應(yīng)譜法能夠滿足施工圖設(shè)計(jì)要求. 通過(guò)罕遇地震下的彈塑性時(shí)程分析,對(duì)基底剪力、彈塑性層間位移角、構(gòu)件承載力進(jìn)行了復(fù)核,結(jié)果表明,整體結(jié)構(gòu)在罕遇地震下表現(xiàn)出較好的抗震性能,能夠滿足預(yù)設(shè)性能目標(biāo). 針對(duì)大跨度懸挑區(qū)域,進(jìn)行了樓板舒適度分析,結(jié)果表明,結(jié)構(gòu)設(shè)計(jì)滿足舒適度要求.

Abstract: The L5 forest buildings in Bailuwan wetland adopts steel frame-supporting structure with arc cantilever vierendeeltruss. Based on the mechanical characteristics of the arc vierendeel truss and the comparative analysis of three truss systems,the cantilever truss structure form with vertical herringbone shape bracing between the inner and outer arc vierendeel trusseswas determined. The floor displacement, the maximum inter story displacement angle and the floor shear force obtained fromthe elastic time history analysis under frequent earthquakes were consistent with the results of the response spectrum analysis,which verifies that the response spectrum method can meet the requirements of the construction drawing design. Through theelastic-plastic time history analysis under the rare earthquake, the base shear force, elastic-plastic interlayer displacementangle and member bearing capacity were reviewed. The results show that the overall structure shows good seismic performanceunder the rare earthquake and can meet the preset performance goals. The floor comfort analysis was carried out for large-spancantilever area. The results show that the structural design meets the comfort requirements.

Keywords: steel structure design; cantilever structure; arc vierendeel truss; bucking restrained brace; time-historyanalysis;comfort analysis
