[摘要] 湖州太湖明珠酒店是由兩個(gè)對(duì)稱塔樓通過(guò)連接體形成的巨大環(huán)形結(jié)構(gòu)，單塔采用鋼框架一混凝土核心筒結(jié)構(gòu)體系，連接體采用雙向鋼桁架轉(zhuǎn)換體系。采用ETABS三維計(jì)算軟件對(duì)太湖明珠酒店的結(jié)構(gòu)方案進(jìn)行了分析，得出在這種結(jié)構(gòu)體系下，核心筒剪力墻承擔(dān)了在各種工況下的幾乎全部的水平剪力，且墻體配筋率在規(guī)范允許范圍之內(nèi)；鋼框架結(jié)構(gòu)主要應(yīng)力比控制在0.75之內(nèi)；各種總體控制指標(biāo)均滿足現(xiàn)行規(guī)范；同時(shí)對(duì)雙向轉(zhuǎn)換桁架、空間曲線鋼柱的主要受力性能做了定性的闡述。

Abstract: The Taihu Mingzhu hotel is a super ring structure which is made up by two high-rise steel frame-core systems building contacting by a two-way steel truss. The paper expatiated on scheme analyzing and computing of the Hotel by ETABS, and reached some conclusions. The Shear-wall of core-system bears almost all horizontal shears and the reinforced ratio of shear-wall is within the limits of codes. The stress ratio of steel frame columns and frame beams are controlled under 0.75. All main targets are satisfied codes. The paper also expatiated on the mechanics performance of two-way steel truss and space curve-frame columns.
Keywords: steel frame-core system; ring structure; two-way steel truss; transfer stories; space curve-frame columns
