Structural Performance of Stapled Wood Shear Walls under Dynamic Loads

Abstract eng:
Wood shear walls are the most common element in the lateral force resisting system of residential construction. Recent developments have made the use of staples, as a sheathing to stud connection, much more feasible and practical. Dynamic cyclic tests of wood shear walls using staples as connectors of sheathing to the studs were performed to determine load and displacement capacities. Enhanced details from standard construction were used to improve the performance of the global system including a double sill plate, a new refined panel corner detail, double staples along blocked edges, and backup bolts for hold-downs. The experiments have shown that the stapled wood shear walls with the enhanced details performed at a level above that allowed by the International Building Code-IBC (ICC 2006) regarding peak load capacity but slightly less regarding peak drift capacity.
