摘要
考虑材料非线性和几何非线性 ,应用有限元法分析了空间KK型钢管相贯节点的应力和塑性区分布规律、节点变形等受力性能 ;揭示了影响管节点承载力主要参数以及这些参数与承载力的关系 ;提出了空间KK型钢管节点承载力稍低于平面K型的观点 ,为工程设计提供了有益的参考 .同时验证了用有限元模拟试验的可能性 .
In this paper, the ultimate bearing capacity of circular tubular KK_joints is investigated nume rically by using the finite element method and with close reference to both material nonlinearity and geometrical nonlinearity. The distribution of stress, plastic_zones and the joint deformations are analyzed. The influence of geometric parameters on the ultimate bearing capacity is investigated and explained graphically. The paper presents the view that the ultimate bearing capacity of circular tubular KK_joints is a little lower than that of K_joints is put forward. Some useful references for projects design are presented and the feasibility of using the finite element method in simulating experiment is proven.
