- Abstract
The research project presented in this study aimed to study the effect of bolt numbers and patterns on protected and unprotected concealed steel-glulam hybrid connections. Fifteen full-scale wood-steel-wood (WSW) connections were experimentally examined: five ambient and ten fire resistance experiments. Four and six steel bolts in two different patterns were arranged to form four different connection configurations that were experimentally examined. Also, each connection configuration was tested with and without fire protection of the steel components using wood plugs. Ambient specimens were tested under gradually increased monotonic loads until failure; whereas the other specimens were subjected to elevated temperatures that followed CAN/ULC-S101 standard fire, while being loaded to 100% of the ultimate design load capacity of the weakest connection configuration. The experimental results revealed that, the protected connections exhibited a failure time that is about 20 minutes more than that of the unprotected connections.
