In the past few decades, the effects of accidental explosions and risks associated with terrorist attacks on structures have become a topic of interest for civil engineers and researchers. Although intensive research on the behaviour of concrete, steel and masonry subjected to blast loads was conducted, information on the behaviour of timber structures is still limited to mostly research on impact loads. The objective of this paper is to establish blast response limits for light-frame wood stud walls for different damage levels under blast-induced shock waves. Following analysis using the single-degree-of-freedom modelling approach and experimental testing, it was found that a shock tube can effectively be used to assess the damage levels for wood stud walls. The experimental data agreed with the predicted responses using SDOF models with appropriate combined material models for studs and sheathing.
