Excerpts from Antiterrorism Design Requirements for Cold- Formed Steel Framing .

resistant construction in the private sector, that could change. “There’s nowhere to go but up,” Ford says. Made by rolling or pressing steel into semi-finished or fin- ished goods at relatively low temperatures, cold-formed steel is affordable, easy to use, and can be erected much quicker than masonry or concrete. The material is straighter than wood, and is resistant to termites and fire. While there are many applications for cold-formed steel, its primary use is in construction for curtain walls and partitions. Accord- ing to Rahman, it can be used as the primary structural sys- tem for buildings as tall as seven or eight stories. Pulling together expert information from a dozen sources, the technical note is touted as an authoritative resource on cold-formed steel and its application to blast protection of “You don’t need much to come up with a design to save people.”

In recent years, the DoD Unified Facilities Criteria program has developed documents to help walk a designer through the process; however, a considerable confusion still exists.” Pat Ford, technical director at the Steel Framing Industry Association and principal at Matsen Ford Design Asso- ciates in Wisconsin, says blast standards for cold-formed steel are still relatively knew, as are antiterrorism design and construction guidelines in general. “Understanding and implementing antiterrorism requirements into cold-formed steel framing design can be a daunting task for a designer.” That being the case, a technical note like the one created by Rahman and O’Laughlin is important because, as Ford says, “Not many people [builders and designers] know how to do it.” While there’s currently not much of a demand for blast-
