Tension Bracing (CDTB)

Prevents flange rotation and support flanges in compression

Tension Bracing is used to prevent joist compression, flange lateral movement, and rotation. These tension ties are used as an alternative to traditional block and strapping. Tension ties are traditionally used with wood framing, but can also be used with conventional C-joists.

Tension bridging has a right-angled section with flattened ends 1 inch (25.4 mm) wide, with pre- punched screw holes at each end. As a general rule, floor bracing or bridging is installed at 8' o.c. maximum.

Tension bracing is secured to the top of the first joist and to the bottom of the next joist. The process is reversed so an “X” is formed in each joist bay. Tension bracing must be installed in pairs using two #10 screws at each end. The process is repeated in each joist bay.
