ABSTRACT:
A shear wall of a building is tied down to an underlying concrete slab by a single tie rod at each end of the wall. The upper end of each rod is secured to a bracket attached to a shear wall stud, and the lower end of the rod extends through a slot in the upper flange of a channel-like lower bracket. The lower flange is provided with a plurality of slots extending in a common direction and up through which bolts anchored in the concrete foundation extend. The upper slot in this lower bracket extends in a direction at a right angle to the lower slots, and at least one of the several slots extends lengthwise of the shear wall. The slots in the bottom of the lower bracket permit its adjustment on the foundation to position it for receiving the lower end of the rod in the upper slot.
