Trusses are designed for specific loading, geometry and support conditions. Under no circumstances should any component of the truss be drilled, cut, removed or modified in any way without prior approval from the truss Steel Cross-Bracing Roof Trusses (light), 1"x1"x4mm angle bar and 10mm square bar 7.2.10 Strutting for attic trusses and cut roofs that form a floor Strutting to attic trusses shall be provided to support the applied loads and self-weight without undue movement or distortion. Strutting should be provided: during construction. The roof trusses can only provide lateral load resistance after the roof joist, roof deck diaphragm and the longitudinal braced frames are in place. The open-web steel joist between the columns has insufficient strength to deliver the lateral loads to the longitudinal vertical bracing without a completed roof deck diaphragm. While roof trusses are the major components for the structural roof system, permanent bracing is also required to complete the system and ensure that it performs as designed. In this Tech Note, the basic requirements and design parameters for permanent bracing of cold-formed steel roof systems will be reviewed.
