中文摘要：长江传媒大厦是武汉新建的地标性建筑,建筑总高度为238.1m,在标高205.30m的大屋面之上是宽度为29.25m、高度为33.45~36.85m的锥形装饰钢结构,重达1 000t。施工过程中由于高度过高和塔吊起吊能力受限,采取了"分榀拼装,累积滑移"的施工方案,但对于这种超高层建筑顶端钢结构滑移项目,风荷载影响很大。巧妙地利用"不倒翁"原理,通过设置高低滑移轨道,有效降低了高空中风荷载带来的不利影响,带来了良好的安全保证和经济效益,以期为其余同类高空项目的施工安装提供参考。

外文摘要：The Changjiang Media Building is a new landmark building of Wuhan. It has a total height of 238.1 m. There is a large roof above the elevation of 205.30 m. The roof is a 29.25 m wide,33.45 m to 36.85 m high conical decorative steel structure,and the weight is up to 1 000 t. The steel structure components have big cross sections, thick plates,and heavy weight,and thus the construction scheme ＂segmental hoisting, truss assembly, accumulative sliding＂ is mainly adopted. Using sliding rails with elevation difference, the negative influence of wind loads is effectively reduced, and the safety and economic benefits are guaranteed. In this paper, sliding construction key technology of this project is introduced in detail,and this can provide a reference for similar steel structure construction.
