A recently completed testing project conducted to evaluate optimized structural roof-to-wall attachment solutions demonstrated the effectiveness of wood structural panels in restraining high-heel trusses against rotation. This study was designed to further evaluate the performance of OSB wall sheathing panels extended over the high-heel truss in resisting combined uplift and shear forces. Five full-size roof-wall assemblies were constructed with extended OSB wall sheathing and each was tested under a different loading combination. Our test results indicate that using extended wood structural panel wall sheathing as the primary connection element at the roof-to-wall interface of energy trusses can provide a continuous load path in both the shear and uplift directions and can be considered a viable option for residential construction in most areas of the country.
