空间结构铸钢节点的应用研究进展

Research Progress on Cast Steel Joints in Space Structures

铸钢节点以其独特的优势在工程中得到了广泛应用,国内外很多重大工程在关键部位均采用了此类节点。结合近年来国内外的研究进展,从应力分布特点、构造细部、疲劳和刚度等方面总结了铸钢节点的应用研究现状,并对铸钢节点的相关方面进行了分析讨论,指出铸钢节点在发展过程中的难点与问题。最后,对铸钢节点有待解决的问题给出建议并对其未来需要研究的方向进行展望。

The east steel joint has been widely used in architectural engineering because of its unique advantages. Therefore,it is applied in many projects home and abroad. In this paper, the recent research progress on the application of cast steel joints is summarized in four aspects, including the stress distribution characteristics, structural details, fatigue and rigidity. Some related topics on the cast steel joint are also discussed in this paper, and a few important and complex problems in the future development are pointed out as well. At last, suggestions are provided for resolving problems on cast steel joints, and future research directions are proposed.
