Lateral bracing of web ties

If the truss is heavily loaded and has deep slender web elements, the designer may specify that the webs be laterally braced. The timber web tie links the centre of all webs together (just as battens do for the top chords).

The steelbrace stabilises the rectangular shape of the plane formed by the webs.

Diagram of part of a roof truss with steelbraces. Braces to cross at mid-length to match tie. Angle of brace to web ties to be between 30 and 45 degrees. Web tie, as specified, fixed to each truss web at even spacing with two 65 mm nails. Bend steelbrace over chord and fix with five nails to face of chord. Typical both ends of brace. Two nails to web of each intersection and truss.
