Can You Live Without Them? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Steve Leyton Sent: Thursday, March 25, 2010 3:57 PM To: [email protected] Subject: RE: Seismic Restraint Standards What edition of ASCE are you referring to as "the latest"? To my knowledge, the 2005 is the latest and sections 13.6.8.2 and 13.6.8.3 speak directly to the "exclusion" as you call it. The 2007 edition of NFPA 13 included revisions, specifically tables 9.3.5.3.2(a) and (b), as well as Table 9.3.5.6.2 and the associated steps in the calculation procedure, that meet the prescribed "force and displacement requirements of Section 13.3.1 and 13.3.2", if I'm not mistaken. All that taken together means that a system designed with seismic bracing in accordance with NFPA 13, 2007 or 2010 editions in fact DOES meet ASCE 7, and in turn the requirements of Chapter 16 of all IBC editions up to and including 2009.

In the latest edition of ASCE 7 the NFPA 13 seismic bracing exclusion was removed from ASCE 7. Be aware of the version of the IBC that is being enforced in your area of operation since the IBC is considered the legal code which tells the designer, owner and design professionals what the requirements are for the building based on occupancy, construction type, ground floor area, building height and exposure to building.

For mechanical piping, plumbing, duct, etc, SMACNA. For Fire Protection, NFPA 13. SMACNA isn't referenced in the NFPA INSTALLATION Standard, because 13 has it's own rules to follow. SMACNA is also no longer referenced in the IBC as of the 2003 edition. ASCE 7 was established as the accepted standard. However there was some verbiage placed in the Code which would permit acceptance of other design standards if approved by the AHJ. So if the MEOR wants to apply SMACNA to Mechanical piping and duct systems he needs to request permission from the AHJ to use that standard. But as previously stated, NFPA 13 is the applicable standard for design of seismic bracing for Fire Protection service piping not SMACNA. Craig L.

Sprinkler specs often refer to General Mechanical. Question: Does NFPA 13 seismic bracing requirements take precedence over SMACNA? How was the battle won with the MEOR when he says SMACNA is the preferred standard for bracing of piping systems? Any comments would be appreciated.
