Right. Provisions for seismic protection of buildings and building systems in the IBC and also in NFPA 13 are now all based on ASCE 7. We rolled a new code on 1/1/14, so moved forward to ASCE 7, 2010 here in CA. ASCE standards establish parameters for when a building is required to be seismically engineered. The structural engineer of record for a given project is usually charged - sometimes in conjunction with the soils engineer - with determining whether a particular parcel is subject to those provisions. As Travis says, seismic has changed; IMHO, it's not for the sprinkie to determine if seismic protection is required, only to verify with the SEOR or through the construction documents whether or not it's required.

Seismic has changed DRASTICALLY from what we used to do. The SE will have to provide you the structural design category and the Ss for the project. Hopefully it is SDC of A or B and you don't have to worry about anything. But, it is definitely no longer 40' / 80' and 4 way every change in direction.

Is it Seismic Category C or higher. If so, bracing is required on fire sprinkler systems. I don't think the seismic maps really apply any longer. You need to know the Seismic Design Category, then you need the Ss values so you can calculate your bracing. > > Travis Mack, SET > MFP Design, LLC > 2508 E Lodgepole Drive > Gilbert, AZ 85298 > 480-505-9271 > fax: 866-430-6107 > email:[email protected] > > On 1/23/2014 9:15 AM, Richard Mote wrote: >> Can someone with experience in the area tell me if Seismic bracing is required in Fredrick Maryland? (21701) According to the maps I found online at appears to be the same seismic category as central PA, but not having worked in the area before I wanted to be sure there wasn't some local requirement. >> >> Richard L.
