As cross-laminated timber has become an increasingly popular construction material, its use as a shear wall element has also demanded attention. Primary obstructions to the use of CLT shear walls have been the lack of an economic connection type that does not compromise the structural integrity and has the robustness that CLT shear wall panels deserve. Dovetail connections provide a great option for the connection of CLT shear walls. With more experimentation, the optimal dovetail geometry can be further developed. The small-scale testing done in conjunction with this report proved that very deep pins and tails will result in bearing failures at the joints. If the depth of the pins and tails is too short, the results from tests show that the dovetail will fail in bending along the neck of the joint. In order to duplicate the results of this report it is important to choose the correct geometry of the test-specimen.
