摘　　要：铸钢节点以其拓扑形状适应性强、受力性能好、施工方便等特点,适用于轻型管状结构桥梁。轻型桥梁中的铸钢节点按其连接作用类型可分为:铸钢交汇节点、铸钢支点以及钢-混结合面的铸钢齿状节点等。结合铸钢节点在轻型桥梁结构中的应用优势,介绍其在桥梁中的应用情况,并探讨桥梁铸钢节点需要进一步研究的问题。Having the characteristics of excellent adaptability in topological shape, good load- carrying performance and convenient construction, the cast steel joints are suitable for light bridges with tubular components. According to the types of connecting functions, the cast steel joints used for light bridges can be classified into the cast steel intersection joints, cast steel sup- porting joints and cast steel tooth-like joints on steel-concrete conjunction. With reference to the advantages of application of the cast steel joints to light bridge structures, the application of cast steel joints to bridges is addressed and the problems of the cast steel joints required further study are discu＇ssed.
