Steel Roof Truss Bracing
Easier to install than wood bracing.
Steel roof truss bracing. There are several reasons for truss bracing in a roof or floor structure. The diagonal members transfer the restraint forces to the level of the top chord where the general roof bracing is provided. Roof bracing is a pre punched v shaped component that fixes in an x or v pattern to the top of the top chord to firmly brace roof trusses to the building frame. Such bracing allows the buckling length of the bottom chord to be limited out of the plane of the truss to the distance between points laterally restrained.
To strengthen the roof system truss clustering cross bracing and wind bracing is recommended at both end of the buildings and every 20 for longer span buildings. During construction before all of the components of a truss system are in place bracing acts to hold members upright straight and in place. Truss clusters for maximum strength this image shows a cluster of three trusses tied together. Thd sku 105802.
Roof bracing must be applied in opposing directions with the number location and tie down of bracing units to be determined as described in the relevant standard. This temporary restraint typically may not be the responsibility of the structural engineer. Purlins 24 oc are typical along with the bottom bracing shown.
