摘要: 布吉文體中心項(xiàng)目采用鋼框架結(jié)構(gòu)體系,存在扭轉(zhuǎn)不規(guī)則、凹凸不規(guī)則、樓板不連續(xù)、尺寸突變、構(gòu)件間斷(柱轉(zhuǎn)換)、局部不規(guī)則(躍層柱、斜柱)等 6 項(xiàng)一般不規(guī)則項(xiàng),扭轉(zhuǎn)偏大 1 項(xiàng)顯著不規(guī)則項(xiàng)。 對(duì)超限不規(guī)則項(xiàng)進(jìn)行分析,分析結(jié)果表明:大跨桁架的斜腹桿對(duì)結(jié)構(gòu)整體剛度影響很小,不影響鋼框架結(jié)構(gòu)體系判定,不作為支撐結(jié)構(gòu);雖然局部存在單跨框架,但整體結(jié)構(gòu)不屬于單跨框架結(jié)構(gòu);通過樓蓋有效拉結(jié)可實(shí)現(xiàn)整體結(jié)構(gòu)受力,結(jié)構(gòu)具有足夠的安全冗余度;通過扭轉(zhuǎn)效應(yīng)分析,說明扭轉(zhuǎn)偏大的構(gòu)件具有足夠承載能力以抵抗扭轉(zhuǎn)帶來的不利影響,且構(gòu)件扭轉(zhuǎn)偏大,實(shí)際的整體扭轉(zhuǎn)角很小,扭轉(zhuǎn)效應(yīng)的影響很?。煌ㄟ^大跨空間框架的梁柱節(jié)點(diǎn)的合理設(shè)計(jì),可滿足強(qiáng)柱弱梁、強(qiáng)節(jié)點(diǎn)弱構(gòu)件等重要抗震概念和抗震性能目標(biāo),達(dá)到良好的結(jié)構(gòu)抗震性能,各項(xiàng)控制指標(biāo)均滿足要求。

Abstract: Buji Culture and Sport Center project adopts steel frame structure system. There are six general irregularities,including torsional irregularity, concave convex irregularity, floor discontinuity, size mutation, component discontinuity(column conversion), local irregularity ( through floor column, inclined column), and one significant irregularity ofexcessive torsion. Out?of?limit irregularities were analyzed. The analysis results show that the diagonal web member of long?span truss has little influence on the overall stiffness of the structure, does not affect the judgment of steel frame structuresystem, and is not used as a brace structure. Although there is a single span frame in local, the overall structure is not asingle span frame structure. The stress of the overall structure can be realized through the effective tie?in of the floor, thestructure has sufficient safety redundancy. Through the analysis of torsion effect, it shows that the member with large torsionhas enough bearing capacity to resist the adverse effect of torsion. The torsion of member is large, the actual overall torsionangle is small, and the influence of torsion effect is small. Through the reasonable design of beam column joints of long?span spatial frames, important seismic concepts and seismic performance objectives such as strong columns and weakbeams, strong joints and weak members can be met, good structural seismic performance can be achieved, and all controlindexes meet the requirements.

Keywords:Buji Culture and Sport Center; out?of?limit irregularity; local single span frame; large torsion; seismic concept;performance objective
