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 SBCA 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.

The requirements discussed are considered standard in the industry and are presented as a guide. Specific designs should be confirmed with the local building authorities, who may have unique regulations not addressed in this report. The guidelines provided in this SBCA Research Report are not intended to exclude alternative solutions for specific projects that have been designed by a qualified Registered Design Professional.
