A new design of a tube to gusset plate K-joints for tubular structures is proposed in order to permit rationalization of joints. The eccentric joint where the intersection of the gravity axes of branch pipes are shifted to the gusset plate side can increase the degree of freedom of design. In the previous report, the strength equation for an eccentric joint was found and its effectiveness was demonstrated. In the current study ,the elastic and plastic behavior of a main pipe at an eccentric joint was found by the FEM. The analysis result corresponded to the experiment result. The new method surely is effective, because the uniformity of stress distribution in cross section of a main pipe is better at the negative eccentric joint than at a noneccentric joint.
