Ask the engineer, really the only one that can answer. Chris
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Cliff Whitfield Sent: Wednesday, November 10, 2010 4:59 PM To: [email protected] Subject: Seismic Question I have an unusual situation on a project and would like some opinions. We are currently doing a project where seismic bracing has been specified for 'blast protection' (or something like that). The project is not in a zone that would otherwise require seismic protection. So here is my question. Are restraining straps required to be installed on the beam clamps? Now before you answer, consider this - NFPA 13 2007 - 9.3.7.1 - C-type clamps ... used to attach hangers to the building structure IN AREAS SUBJECT TO EARTHQUAKES shall be equipped with a retraining strap. Ok, now what is your opinion?
