In this paper, the ultimate strength of plane circular tubular K_joints is investigated numerically by using the finite element method and close reference to material and geometrical nonlinear properties. The distribution of stress, plastic_zones and the joint deformations are analyzed. The influence of geometric parameters on the ultimate strength is investigated and explained graphically. By comparison of the FEM computational results with those of the current PRC codes, the deficiency between them is found out and some useful suggestions for modifications of the current PRC codes are presented. Furthermore the possibility of using the finite element method in simulating experiment is proven.
