The introduction of CrossLaminated-Timber (CLT) has added to the interest in wood-based structural systems. Structures need to be designed for appropriate capacity, stiffness, and if applied in seismic zones, ductility. As CLT panels are rigid, the desired ductility for seismic design must be obtained from the connections. Self-Tapping-Screws (STS) are the state-of-the-art in connector technology for CLT structures; however, current North American design standards have no guidelines for STS in CLT. The research presented in this paper examines the performance of 3-ply CLT panel assemblies connected with STS under quasistatic monotonic and reversed cyclic loading. Different joint types were tested: traditional surface spline with STS in shear and half-lap joints with STS in either shear or withdrawal, along with two novel assemblies using STS with double inclination of fasteners, and a combination of STS in withdrawal and shear. The results of 21 cyclic tests confirmed that: 1) connections with STS in shear can be ductile and can reach large relative displacements; 2) connections with STS in withdrawal are much stronger and stiffer, however, such joints fail at small displacements; and 3) connections that use a combination of STS in withdrawal and shear can allow for high strength, high stiffness and relatively high ductility.
