Abstract
AbstractConnections of steel‐structures under dynamic loads need to be slip‐resistant according to EN 1993‐2. Bolted connections without slip can be realized with fitted bolts, preloaded high strength friction grip (HSFG) bolts or injection bolts. Injection bolts are particularly advantageous because the increased effort required for reaming the holes for fitted bolts or for special surface preparation for HSFG bolts can be avoided. The paper focuses on the experimental analysis of connections with non‐preloaded and preloaded injection bolts according to EN 1090‐2. Different resins and curing conditions are considered, as well as different surface treatments or friction coefficients. Thus, the interaction between the slip resistance and the bearing resistance of preloaded injection bolts is investigated more detailed.
