Webinar on Progressive Collapse Design in Cold-Formed Steel Structures
$100.00
Continuing Education Credits Available – 1.5 PDH Credits
Progressive collapse guidelines for DoD buildings were first introduced in 2001 to provide design requirements to reduce the potential of disproportionate collapse for new and existing DoD facilities in an extreme blast event. The guidelines are published in the Unified Facilities Criteria UFC 4-023-03, Design of Buildings to Resist Progressive Collapse, and are applicable to buildings (3) stories and taller. Since cold-formed steel (CFS) framing is a potential construction material in mid-rise load bearing wall structures for DoD facilities, it is essential for CFS engineers to learn practical methods to analyze and design CFS framing to resist progressive collapse. This presentation will introduce the main concepts of structural design to mitigate the effects of progressive collapse in buildings, then will review IBC building code and UFC 4-023-03 requirements and design methods for progressive collapse, then will discuss the differences between the direct and the indirect methods of design. Focusing on CFS load bearing wall structures, the presentation will discuss how to qualify the structural components of the building (walls, floors and roof) for the progressive collapse analysis and what analysis/design tools to use. A worked design example for a multi-story building will be presented and discussed with a focus on how to deal with sizing framing members and connection details.
