This study investigated lateral connection behavior of a single shear connection between a molded core sandwich panel produced with wood strands, and solid sawn lumber. A continuous thread self-tapping screw and common nail were the fasteners evaluated. Connection assemblies with self-tapping screws showed much greater stiffness, yield load, and load-carrying capacity than nailed assemblies, indicating that self-tapping screws may be a viable option for connections between wood-based molded core panels and solid sawn lumber.
