This paper presents the methodology and preliminary results of an experimental program, where the behaviour of light-frame wood walls systems under blast loading was investigated. The walls were tested both statically and dynamically and material properties, such as the dynamic increase factor (DIF), were determined. Two different types and thicknesses of sheathing elements, namely OSB and plywood were studied. Preliminary results indicate that there is a significant increase in capacity when the walls were loaded under dynamic loading relative to their static capacity.
