Numerical Analysis of Single Lap Pretension Bolted Joint

Abstract

Due to their superiority, bolted connections are commonly utilized to join numerous building components. When evaluating the impacts of the connections on the behavior and load-bearing capacity of structural systems, it is crucial to understand the parameters that govern the load-carrying capacity of bolted joints. The bearing capacity of single lap and single bolt friction-effect joints are examined numerically in this paper. Through numerical analysis, the variation in the bearing capacity of the joint as a function of the parameters affecting joint capacity, the pre-tension force, and the surface friction coefficient between the joining plates, was analyzed. Accordingly, it has been observed that the pre-tensioning force and friction coefficient both increase the joint's capacity in a comparable manner. The results demonstrate that the bearing capacity of a slip-critical joint can be enhanced by applying roughening techniques to the friction surfaces of the plate.
