Design Considerations for Using Adhesives in Shear Walls

Abstract

The results of earthquake tests of light-frame, wood shear walls conducted by several researchers are reviewed. The effect of using adhesives to attach the sheathing material to the framing is considered, specifically, potential problems due to the adhesive strengthening and stiffening of the wall system when subjected to an inertial loading such as an earthquake. None of the current design and building codes used in the United States address the use of adhesives, and engineers may design unsafe structures. Change in probable failure modes from the traditional ductile yielding of the nail connections between the sheathing and the framing to the anchorage connections or adjacent structural components is highlighted. Recommendations for changes that should be made to the building and design codes are suggested. Changes to the seismic design procedures only are recommended and the improved performance of adhesives in shear walls subjected to wind or other applied loads is acknowledged.
