大直径焊接空心球节点承载力研究综述

摘要

Previous research on bearing capacity of large-diameter welded hollow spherical joint was covered in this paper from three aspects,which are test,theory and finite element methods.This paper summarized existing research on bearing capacity of welded joints with kinds of stiffening rib.Some suggestions were proposed for researchers to move on.%总结了大直径焊接空心球节点承载力的已有研究,从试验、理论和有限元方法三方面分别阐述了大直径焊接空心球节点承载力的发展历程。通过对不同加劲肋方式进行分类归纳,比较全面的概括了现有文献对加劲肋焊接空心球节点承载力的研究。由此得出已有研究存在的问题及不足。
