Well, if your not sure, you need to watch this video. In an earthquake, inadequately Seismic bracing is only one of the five design features that must be provided when doing seismic design for a system. A fire sprinkler system requiring seismic protection is held in place within a building with some combination of sway bracing, restraint hangers, and pipe stands. Bracing Systems provide contractors with high-quality, engineered solutions, which include rigid bracing, cable bracing and rod stiffeners. The risk of fire runs high after earthquakes, most often triggered by broken gas lines, exposed wires, arcing electricity, and fuel spills. Our fastening, hanging and support solutions are known for their high-quality, superior technical performance and simple, intuitive installations. The sprinkler pipe shall be braced using the method in 9. For pipe bracing subassemblies with expected load ratings less than 1000 pounds (454 kg), the initial loading on the sample will be 250 pounds (113 kg). Versatile design allows for attachment at any angle and the ability to be used in a lateral or longitudinal bracing configuration. 3 Where clearance is provided by a pipe sleeve, a nominal diameter 2 in. 8. But there are several additional Flexible components reduce stress during a seismic event by allowing sprinkler systems to move or bend at specific locations. The discussion is not all-inclusive; however, it does include requirements that are either new or commonly overlooked. It calculates the correct bracing loads per NFPA 13 guidelines, Uniform Building Code (UBC) on the map below constitute moderate to high seismic regions where MEP bracing should be provided. FPPI.
