Based on recent fire test results, mass timber groups have adjusted product certification standards to require the use of cross-laminated timber with structural adhesives tested to demonstrate better fire performance.
Based on 2016 tests of a composite cross-laminated timber-and-concrete floor system, architect-engineer Skidmore, Owings & Merrill has released guidance on how to analyze composite timber floors and predict their behavior in wood frames.
Good performance of the cross-laminated timber panels, made by the first certified CLT supplier in the U.S., is expected to have a positive impact on domestic production.
Having recently validated assumptions about floor-system capacities in its timber-and-concrete structural model for a 42-story residential building, architect-engineer Skidmore, Owings & Merrill is planning additional load tests, followed by fire tests, to nail down the viability of mass-timber-and-concrete high-rises.
