Connections are essential elements in any building system as they contribute significantly to its structural stability. Connections in hybrid timber construction would normally fail due to loss of strength in the wood member. To investigate the structural resistance of unprotected hybrid steel-column and glulam-beam shear tab connections when exposed to a real fire, six (6) full scale tests were carried out in this study. This paper presents and discusses the results obtained during the tests that include temperature profiles at sections of the timber beam close to the connections and the mid-span, as well as the failure modes and charring rates for each shear tab connection assembly. The influence of parameters of load ratio and the configuration of the shear tab connection considered are also presented.
