摘要 上海环球金融中心大厦高101层,结构高度492m,高宽比8.49,拟建成为世界上结构主体最高的建筑物。大厦采用了三重结构体系抵抗水平荷载,它们由巨型框架、钢筋混凝土核心筒及构成核心筒和巨型型钢混凝土柱之间相互作用的伸臂桁架组成;核心筒竖向不连续,由低筒、中筒和上部筒3部分组成;二对角巨型柱在42层以上开始分叉形成倾斜曲面,巨型斜撑只设置在垂直立面上,且采用单向支撑。根据我国《高层建筑混凝土结构技术规程》(JGJ3-2002),该建筑总高超过了型钢混凝土框架-钢筋混凝土筒体最大高度190m的限值,同时高宽比超过了设防烈度7度地区为7的限值。为研究它在地震作用下的抗震性能,进行了缩尺(1/50)模型的振动台试验。试验结果表明,该结构体系合理,具有足够的水平刚度,在地震作用下位移反应不大,扭转效应比较小,满足我国抗震设防要求。 The height of 101-storeyed Shanghai World Financial Center is 492m. This makes it possible to be the tallest building in the world. Its aspect ratio of height to width is 8.49. Three parallel structural systems composed of the mega-structure, the reinforced concrete and braced steel services core and the outrigger trusses, are employed to resist lateral loads. The reinforced concrete consisting of lower core, middle core and upper core are not continuous vertically. Instead of providing braced frames at the exterior curved surfaces of the building, a single-diagonal system is adopted on the vertical faces in the mega-structure frame. According to the technical specifications for concrete structures of tall building (JGJ3-2002), the height of the building clearly exceeds the stipulated maximum height of 190m for a composite frame/reinforced concrete core building. The aspect ratio also exceeds the stipulated limit of 7 for a basic seismic intensity of 7. A scaled model was made and tested on the shaking table to study its dynamic characteristics, seismic responses and evaluate its capacity to withstand earthquake.The test results demonstrated that the adopted system is an ideal solution for the building to withstand earthquake. The inter-story drift and the overall torsion meet the requirements regulated by Chinese design codes.
