Fire testing conducted to justify provisions for three new mass timber construction types in the 2021 I-Codes was performed using an earlier generation of cross-laminated timber (CLT). U.S. model building codes now require compliance with the enhanced fire performance criteria of PRG 320-18. To investigate fire-safe implementation of visible mass timber in tall buildings constructed with PRG 320-18-compliant CLT, the U.S. Forest Service funded a 2-year research program starting in 2019. Test results and conclusions from this research program are presented in this webinar, followed by a discussion of ways in which the test results are being applied in tall mass timber building design and regulation.
- State the need for follow-up testing performed at the Research Institutes of Sweden (RISE).
- Describe the test configuration, assumptions associated with opening factors, fuel loads and fire extinguishment criteria.
- Understand the configurations of exposed mass timber walls and ceilings which contribute to self-extinguishment of fires in compartments.
- Summarize results and describe ways in which the findings from the RISE research are being applied in support of ICC G147-21 and can serve as justification for alternative approvals for tall mass timber building designs.
