Abstract: Anny Regulation 420-70, Buildings and Structures, requires the inspection of trusses, roof framing, and other structural items every 2 to 5 years. In some cases, detailed evaluations of heavy wood structures are needed as subsequent steps of inspection to check structural integrity under design loads specified by current building codes. An evaluation procedure for wood structures differs from conventional methods used in steel, concrete, and masonry structures because, in wood construction, the allowable stresses used in design may not represent the actual strength ofmembers in existing structures. This study documented comprehensive procedures for the structural evaluation of heavy wood truss structures and identified commercially available nondestructive tests that can be used to determine the mechanical properties of existing members.· Also investigated were issues related to modeling of wood structures necessary to create models that can reproduce the behavior of the prototypes.
