Fire resistance of primary beam - secondary beam connections with full thread screws

Within the German research project “Fire resistance of primary beam - secondary beam connections in timber structures” solutions for a fire-safe design have been developed. The project concentrated on connections with self-tapping full thread screws and joist hangers. This paper describes the investigations, calculations and experiments on the former type of connections. Herein, a series of loaded fire tests and numerical simulations were conducted with the objective to develop design rules and determine the load-bearing capacity.     «
