Fire behaviour of mass timber beam-to-column hybrid connections – A state-of-the-art review
Osama (Sam) Salem
Abstract. Analyzing and designing timber connections in fire conditions presents a significant challenge in timber buildings. Regardless of the beam-to-column connection configuration, connections are considered the weakest link in a timber building when exposed to fire. This paper presents state-of-the-art research on the structural fire performance of mass timber hybrid connections, providing valuable insights for the design and construction of timber buildings. The behaviour of different mass timber beam-to-column hybrid connections investigated through fire endurance experiments over the past decade in the Fire Testing and Research Laboratory at Lakehead University (LUFTRL), Ontario, Canada, are addressed. Comparative analyses of the experimental results obtained with emphasis on various aspects, including the connections’ moment-resisting capabilities and failure modes, the influence of fire protection application, and the utilization of STS as a strengthening technique on the structural performance of timber connections in fire conditions, are discussed.
