As the Strong-Rod™ Anchor Tiedown System (ATS) for shearwall overturning restraint undergoes tension loads, it is important to specify adequate compression elements to resist the compression loads. They comprise a pair of posts or built-up studs at each side of the Strong-Rod ATS system. Simpson Strong-Tie has provided two options for post configurations. The configuration is determined by the Designer based on design and construction preference.
Specifications of studs and posts are the responsibility of the Designer. The distribution of edge nailing is important to transfer the loads appropriately. The following are some examples of recommended nail distribution between posts.
Symmetrical Posts: An equal number of posts or studs on each side of the Strong-Rod™.
Moment Arm = center of rod to center of rod
Nailing Example: (4) total compression members: 2" o.c. edge nailing x 4 = 8" o.c. nailing at each compression member.
