Seismic bracing notes
- A seismic brace restrains the pipe against sideways (lateral) or lengthwise (longitudinal) movement during an earthquake. A hanger only carries the pipe weight and does not brace it.
- A lateral brace and a longitudinal brace use different pipe clamps, and a clamp that does both is also available. The design shows which one goes where.
- The load a brace can take depends on its angle to the horizontal, the brace pipe size and length, and the fittings used at both ends. Steeper braces take more load for the same length.
- Brace locations, spacing and design loads come from the project design, usually to NFPA 13 or the local code, not from the product catalogue.
- Fix the brace to structure that can carry the load. Check the beam, slab or anchor rating before specifying.
FM Approval notes
- HOOGO seismic bracing is listed by FM Approvals. Seismic sway braces are assessed under FM 1950, and pipe hanger components under the FM 1951, 1952 and 1953 series.
- An approval covers specific products, pipe sizes, brace angles and load ratings. It does not cover a different size, part or combination.
- Use only the parts and sizes shown in the current FM Approval Guide listing, and keep the brace and its clamps as one approved set.
- Listings change. Check the current FM Approval Guide entry and the model number before you specify a product, and ask us for the latest approval documents.
