Experimental study on the mechanical behavior of high strength bolted friction type joints with extremely thick plates and many bolts in a line

Abstract

Resent years, from the viewpoint of rational fabrication of the steel bridges, there are some examples to adopt extremely thick plates more than 75mm for primary members. In case of joints with such thick plates by using high strength bolted friction type joints, the number of bolts in a line along the member axis might be more than 10. However, the mechanical behavior of such multiple joints is not clear. In this study, the experiment for the joints with extremely thick plates and many bolts in a line has been carried out. And discussed herein is the mechanical behavior of such joints based on the experimental results.
