This paper deals with the fire resistance of primary and secondary beam connections in timber structures.
This paper describes a series of unloaded and loaded furnace fire tests in different configurations of these types of connectors.
The main objective is the fire safety design of joist hangers and full thread screws.
Design recommendations are given.
The authors would like to acknowledge both the students and technicians at TU München for their help assembling the specimens, thank GH-Baubeschläge GmbH, SPAX International GmbH and Merk Timber GmbH for the fasteners and beam specimens, and thank the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) and the Federal Office for Building and Regional Planning (BBR) for funding this research project in the German research program “Zukunft Bau”.
