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. Last week, SOM also issued information, based on a method just developed, on how to use composite CLT floors with steel frames.
The guidance, released in two reports on Dec. 4, is a continuation of SOM’s Timber Tower Research Project, begun in 2013. The aim of the effort is to develop design guidance and codes for the use of composite CLT in all structures.
