Installation
Strap bridging for bottom of floor joists
Spacing of bridging must be calculated based on the required strength. In general, bridging is installed at a maximum of 8' O.C. spacing pendicular to the joists. For example, an 18' joist span would require two bridging runs at 6' O.C. spacing.
Where the sub-floor or decking does not provide lateral support, strap must also be installed on the top flange of the joist.
Install immediately after joists are erected and before construction loads are applied.
Solid blocking is field cut from track or joist sections.
Horizontal strap lateral bracing for wall studs
Lateral bracing consists of a field-cut stud or track for solid blocking and steel strap bracing on both flanges of the studs. Solid blocking is placed at each end of the wall, adjacent to wall openings and 8' O.C. maximum. The blocking is attached to each adjacent stud via EasyClip™ E- or S- Series™ clips, or when a track is used, the flanges are cut, the web bent and a minimum 4" overlap is used to secure the track block to the studs. Strap bracing, 2" wide and 20-gauge (33 mil) minimum, is fastened to each solid block and stud flange.
Tension strapping for shear wall x-bracing
Straps are either attached directly to the compression studs or are attached via Gusset Plates. Compression studs must be anchored to the foundation, normally with ClarkDietrich Holdowns. For multi-story construction, the uplift loads are extremely high. It is not uncommon to require 20,000 to 40,000 pounds of uplift force at these connections. Since ClarkDietrich Holdowns are not designed to resist this magnitude of force, it is recommended that embedded plates be installed prior to pouring the concrete foundation. A heavy steel assembly is then welded to the embedded plate and to the compression studs.
Caution: Racking loads are first transferred to the roof or floor decking and then to the shearwalls (X-bracing). The X-bracing then relies on a proper foundation to resist uplift and shear forces. In order for the system to function properly, the load path from the roof or floor deck to the shearwalls to the foundation must be complete. This normally requires additional bracing, blocking, track and rim splices, drag struts, uplift anchors and heavy-duty foundations.
