摘要: 蘇州 360 劇場為表演區(qū)與觀眾區(qū)合為一體的新穎劇院. 通過多方案比選,劇場屋面采用大跨單向鋼結(jié)構(gòu)桁架體系,上承幕墻層鋼結(jié)構(gòu)骨架. 利用 SATWE 及 SAP2000 等結(jié)構(gòu)軟件,按整裝模型、單獨(dú)模型進(jìn)行總體指標(biāo)、構(gòu)件應(yīng)力及變形等計(jì)算分析,驗(yàn)證了大跨重載屋面鋼桁架采用兩端鉸接的合理性,明確了支承框架柱及轉(zhuǎn)換托架的設(shè)計(jì)思路和抗震性能要求,提出了幕墻層骨架與主體鋼結(jié)構(gòu)考慮模擬施工順序一體化設(shè)計(jì)理念;同時(shí)分享了固定球型支座選用及節(jié)點(diǎn)構(gòu)造等設(shè)計(jì)研究成果. 結(jié)果表明結(jié)構(gòu)選型安全可靠、受力合理.

Abstract: Suzhou 360 Theater is a new?type theatre where the audience area is integrated with the performance area. Afterrounds of structural design schemes comparisons, a large?span one?way steel structure truss system was applied to thetheater roof, allowing a steel structure skeleton to supporting the upper curtain wall layer. Using structural softwares such asSATWE and SAP2000, the overall index, component stress and deformation etc. were calculated and analyzed according tothe overall model and the individual model. The rationality of steel truss of large?span and heavy load roof with hingedsupport at both sides was verified. The design idea and seismic performance requirements of supporting frame column andconversion bracket were confirmed. The integrated design concept which considering simulated construction order of curtainwall skeleton and main steel structure was brought up. Meanwhile, the design and research results of the selection of fixedspherical supports and joint structure were shared. The results show that the structure selection is safe and reliable, and theforce is reasonable.
Keywords:Suzhou 360 Theater; large?span steel truss; conversion bracket; curtain wall skeleton; fixed spherical supports
