Study on application of axial force and slip behavior of friction joint with high strength threaded stud welded to thin plate

Abstract

The authors are investigating the joint structure that can be applied only from the upper surface of the composite deck using high strength stud bolt. However, it’s supposed that the slip resistance decrease due to the deformation at the time of stud welding or application of axial force to high strength stud bolt because of the small thickness of steel plate. In this study, the tightening performance, deformation of the steel plate and slip resistance of the friction joint using high strength stud bolt on thin plate are studied by experiments and FEM. As a result, it was found that the axial force to the high strength stud bolt should be restricted. Also, the behavior at tensile loading didn’t differ from the case with large plate thickness.
