| Abstract: | In the paper, nonlinear finite element analysis on the tubular K joints( Square chords and Circular Braces) is carried out. The rules are summarized from the relation between the ultimate strength and parameters . The results show the joint failure mechanisms and Some strengthening solutions are suggested for construction projects. |
