摘要
简述钢管相贯节点的基本类型,揭示目前对于钢管相贯节点极限承载力研究中存在的5个较为常见的疑难问题:钢管节点刚度假定、极限承载力的确定、有限元单元类型的选取、有限元模型约束的模拟和考虑弦杆荷载的规范公式的使用。通过分析,总结了这5个常见疑难问题的解决对策,供相关研究和设计人员参考。
The basic classification of tubular joints is introduced,five difficult common problems in the research of ultimate strength of steel tubular joints are described.The problems are rigidity hypothesis of steel joints, definite of ultimate bearing capacity,selection of element unit type,simulation of model restraint of finite element and adopting of code formulae considering chord load.Through the analysis,solutions to these five difficult problems are summarized,provide reference to correlative researchers and designers.
