摘要

摘要: 空间钢管桁架经常需要采用铸钢件来解决复杂节点的焊接问题。在桥梁、海洋石油平台、风力发动机塔架等疲劳荷载起控制作用的结构中，铸钢件-热轧钢管之间的焊接疲劳性能是需要特别关注的问题。详细介绍国际上铸钢焊接节点在工程的应用、铸钢件材料以及与钢管焊接节点的疲劳性能的研究进展，对一些相关问题进行讨论，指出铸钢焊接节点需要进一步研究的疲劳问题，以期促进我国铸钢焊接节点的工程应用和设计。

Abstract: Welded tubular joints are often used as the main structural components in road and railway infrastructure, offshore platforms and supporting frames of wind turbines,where fatigue is a major concern. Cast-steel joints become an attractive solution to fatigue problems in tubular trusses. The fatigue behaviour of welded cast steel to hot-rolled tubes is the key research focus. This paper provides a summary of the application of welded cast steel joints,the material properties of cast steel and recent development in fatigue behaviour of welded cast steel joint. Future directions are pointed out for this research field in order to promote the application and design of such innovative joints in China.
