When wind uplift restraint systems are installed in accordance with ICC-ES ESR-1161 and the Designer wants to use the bending capacity of both top plates and not just one, top-plate splice reinforcement must be installed at all locations in which there is a discontinuity in one of the top plate members, such as the top plate splice. This is to reinforce the top plate in bending. The splice reinforcement must be attached using Simpson Strong-Tie® 1/4" x 4 1/2" Strong-Drive® SDS Heavy-Duty Connector screws. For top-plate splices that are approximately centered between two adjacent studs in the wall below, reinforcement must be installed as depicted in Figure 1 below. For top-plate splices that are not centered between two adjacent studs in the wall below, reinforcement must be installed as shown in Figure 2 below as well.
