The repair and modification of metal plate connected wood trusses can be a very complicated subject, because each situation must be analyzed individually. This Research Report will give an overview of the fundamental principles behind truss repair that inform the truss designer’s approach in all truss scenarios.

Building Designers need to account for the dead and live loads of fire sprinkler systems, in addition to the other load requirements imposed under the model building codes. Truss Designers are responsible for incorporating the additional load from the fire sprinkler systems into the truss design. The information in this Research Report is applicable to both floor and roof systems. Only vertical loads from fire sprinkler systems are discussed; lateral loads, where required, should be evaluated separately by a Registered Design Professional. 

BCSI Canada includes Canadian references, installation tolerances aligned with local practices, and design related tables consistent with the Canadian design standard.

The National Framers Council will develop standards for framing field operations and management to be used as industry best practices, nationally.
