The American Wood Council Reports Successfully Completing Two Full-Scale CLT Diaphragm Tests

The American Wood Council (AWC) is reporting that they have successfully completed two full-scale cross laminated timber (CLT) diaphragm tests at Weyerhaeuser’s ISO 17025 accredited test facility in Federal Way Washington. The tests will provide strength and deformation data important for the evaluating CLT diaphragm resistance to lateral wind and earthquake forces. The test results will also allow researchers to identify potential opportunities for optimization to further advance use of this new versatile technology in floors and roofs of building structures. In a prepared statement AWC Vice President of Engineering Bradford Douglas, P.E. said, “This research used full-scale seismic testing to test a CLT diaphragm supported by wood members, in this case glued laminated timber framing.”
