WASHINGTON — WoodWorks, in cooperation with the USDA Forest Service Forest Products Lab and Softwood Lumber Board, conducted a second series of blast tests on three existing two-story, single-bay CLT structures at Tyndall Air Force Base—the same structures involved in a series of initial blast tests performed in 2016. While a full analysis will be published early next year, on-site observations are decidedly positive. All structures remained intact under significant explosive loading well beyond their design capacity. “Last year, we tested the structures under their own self-weight,” said Bill Parsons, VP of Operations for WoodWorks. “Those tests were successful and, this year, we built on that effort by testing whether the design methods established as a result of those initial tests needed to be adjusted when the buildings carried typical gravity loads and included different connection configurations, increased panel thickness, and alternate mass timber wall systems.”
