铸钢索夹节点在弦支穹顶结构中的应用

The Application of Cast-steel Clamp Joints to Suspend-dome Structure

铸钢节点作为一种新型的节点形式正越来越多地应用于空间钢结构中。常见的铸钢节点形式有铸钢球节点、铸钢相贯节点及铸钢支座节点。结合武汉体育馆弦支穹顶钢屋盖工程,介绍了另一种铸钢节点——铸钢索夹节点,并对该类铸钢节点的设计、有限元计算与分析进行了探讨,以期给类似工程设计提供参考。

As one of the newest joint types, the east- steel joints are utilized widely in the steel spatial structures. There are three conmaon kinds of cast- steel joint： cast- steel spherical joint, cast- steel tubular joint and cast- steel sustain joint. Combined with the roof of Wu- ban gymnasium, a new kind of structure system of suspend- dome, this paper probes into another kind of cast- steel joint： cast- steel clamp joint, which is expected to offer consults to the projects.
