The stresses in riveted structure and in welded structure show different response under same external force. That difference is mainly due to the slip or deformation of rivet line. When the rivet line is substained to the action of shearing force parallel to its line or normal force perpendicular to its line, the rivet deforms elastically. In the same time, the elastic deformation is produced in the plate around rivet holes by bearing pressure. Consequently, the slip of rivet line is produced. The theoretical calculations reported herein show the dimensional consideration on slip factor (displacement coefficient), effect of rivet joint on the effective breadth of stiffened plate and effect of rivet line (or zone) on the stress concentration around a circular hole in plate under uniform tension etc. The results showed that, in generally speaking, the welded structures show the better efficiency but also show larger stress concentration than those in the riveted structure.
