Performance of beam-To-column concealed connections in standard fires

The majority of structural load-Transferring zones in timber buildings mainly rely on steel connectors. These zones are susceptible to loss of strength under fire conditions, which negatively affects their ability to support applied loads. To investigate the performance of concealed steel-Timber connections under exposure to elevated temperatures that follow the standard time-Temperature curve (CAN/ULC S- 101), beam-To-column assemblies were subjected to static transverse loads equivalent to 30% and 100% of their design moment capacity. This paper discusses the results obtained from these fire resistance tests including the connection failure modes and charring rates
