Best Practice Guidelines for Structural Fire Resistance Design of Concrete and Steel Buildings (NISTIR 7563)

It may be too late to send comments on the report, but it is still available to download and read.  Via the website:

A new draft report released for public comment by the National Institute of Standards and Technology (NIST) provides a comprehensive set of “best practice” guidelines for designing building structures to resist major fires. The document, NISTIR 7563, Best Practice Guidelines for Structural Fire Resistance of Concrete and Steel Buildings, is part of the NIST response to the World Trade Center (WTC) disaster of Sept. 11, 2001, and was developed in conjunction with the agency’s technical building and fire safety investigation of WTC buildings 1 and 2 (the WTC towers) and 7.

Structural fears keep firefighters out of burned building

Fears about the structural integrity of a burned-out six-story office building in which three people perished are keeping firefighters from entering today to see if any more victims remain in the ruins, officials said today.

While there were no reports of anyone missing, the firefighters were waiting for an engineer to give the green light to enter the building again. Its not clear in the article what’s keeping the engineers from making their evaluatlion. I assume they’re waiting for the fire to be put out, after which they could assess if the building is dangerous. Only after this assessment could the firefighters enter the building, room by room, to complete their search for victims.

This got me thinking about a FEMA-sponsored seminar on ATC-20, for rapid post-earthquake safety evaluations of buildings, that I attended a couple years ago. The idea was to equip engineers with a framework to do effective structural evaluations quickly following a disaster. While this fire wasn’t a widespread disaster, it highlights the role of structural engineers in the recovery, following an accident or disaster. For engineers who aren’t building inspectors everyday, but spend most of their time in a design setting, I think the ATC-20 course could be useful.
