The key objective of this study is to analyze full-scale fire-resistance tests conducted on structural composite lumber (SCL), namely laminated veneer lumber (LVL), parallel strand lumber (PSL) and laminated strand lumber (LSL). A sub-objective is to evaluate the encapsulation performance of Type X gypsum board directly applied to SCL beams and its contribution to fire-resistance of wood elements.
The test data is being used to further support the applicability of the newly developed Canadian calculation method for mass timber elements, recently implemented as Annex B of CSA O86-14.
This study was part of a broader project entitled Glulam and CLT Innovative Manufacturing Process and Product Development. The main objective of the current study is to evaluate the effect of CLT panels manufacturing parameters on its fire resistance. More specifically:
§ To evaluate the effect of CLT manufacturing (gluing) parameters on the heat delamination resistance under standard fire conditions;
§ To improve the fire-resistance of the CLT panels.
Innovation in hotspot target equipment used for Infrared (IR) testing reduces risks and logistical challenges. This InfoNote describes the development of a new hotspot prototype for use at the IR grid in Hinton, Alberta.
The objective of the study is to identify current and available solutions for improving the fire resistance of wood I-joists. After an analysis and comparison of these technologies, the most promising solutions will be presented which will be suggested to wood I-joist manufacturers for potential further investigation.
