摘要
节点作为结构的关键部位,其静力承载力及滞回性能的研究具有重要的现实意义。本文采用ANSYS有限元分析计算,探讨了平面K型圆钢管搭接节点的受力性能、破坏模式、滞回性能下极限承载力以及搭接率、内隐蔽部分焊接与否、节点处集中荷载和各几何参数对节点承载力性能的影响。
Joints are the key parts of the structure, their static bearing capacity and hysteretic behavior have important practi cal significance. In this paper, by using ANSYS finite element analysis and calculation, the author discusses the plane K type tubular overlapped joints mechanical properties, failure mode, hysteretic behavior of ultimate bearing capacity and the overlapping ratio, hidden part welding status, concentrated loads on the joints and geometrical parameters on bearing capacity of joint performance.
