In private postings to me in response to my December 3 listserv posting on this subject, several writers asked why I didn't reveal my "vested interest" in FEMA 178. So, in the interest of full disclosure: I was a member of the BSSC committee that worked over three years to produce the document, and chaired the subcommittee that wrote the procedures and commentary on moment-resisting frames. At the time the committee started its work, one hat I was wearing was that of seismic safety program manager for San Francisco overseeing seismic evaluations of many city-owned buildings using ATC-14 criteria. It was the first time that this document was extensively field-tested, and we found situations the document could have done a better and/or clearer job in addressing. My only vested interest then was in seeing that 178 included the lessons learned from the SF experience. The committee initially was charged with reviewing and modifying ATC-14, but the changes in form and substance that the committee felt were needed were extensive, and the committee wound up doing a complete rewrite, which became 178. My "vested" interest today is only to highlight a document that can more readily be adapted into an enforceable standard, thus easing the burden on building officials in jurisdictions that embark on a mandatory seismic retrofit program. This in turn would enhance the chances that more jurisdictions may take such action. FEMA 178 may not be state-of-the-art, but it will help identify and mitigate the more serious seismic hazards, which is always the paramount public-interest justification for retrofit ordinances/programs. After a program is in place, engineers certainly can be guided by FEMA 273, Product 1.2/1.3, etc in situations where their judgement or client needs require that more than the minimum done.
