Blast-Resistant Testing for Mass Timber Exterior Walls – Final Accomplishment Report

TR-17-08.1

UFC 4-010-01 requires that inhabited Department of Defense (DoD) buildings constructed of mass timber structural systems be analyzed for airblast loads. As of the summer of 2015, there was a lack of Test data documenting mass timber system response under the strain rates imposed by airblast loads. Thus, the primary objective of this effort was to perform testing that would demonstrate the capability of mass timber systems to resist airblast loads. Two mass timber systems were investigated as part of this effort: cross-laminated timber (CLT) and nail-laminated timber (NLT).
