摘要
青岛体育馆属多功能的大跨度公共建筑。屋盖由落地交叉拱与两个不对称的鞍形曲面索网组成,上铺轻质屋面板。该馆建筑造型新颖、独特,结构设计及施工的难度较大。本文将结合工程全面介绍索网屋盖的设计和施工,其中,重点介绍索网结构中的绷索成型,预应力张拉和不对称结构的处理等关键环节的计算原理、实施方法以及实际效果。
Qingdao sports hall is a large span multi-functional public building. The roof is composed of two crossed arches on the ground and two-saddle unsymmetrical cable-net, on which there is light weight roof sheathing. The type of structure is innovative and unique, and the design and construction are rather difficult. This paper introduces the design and construction of this kind of cablenet roof, with the emphasis on tying of the cable-net along the curved surface of roof, calculation and implementation in tensioning of cables and treatment of unsymmetrical structures, their practical effects as well.
