Progressive collapse occurs when a single localized failure triggers widespread damage or even total structural collapse. Preventing this requires careful structural analysis to identify vulnerabilities and proactive design strategies to strengthen at-risk areas and create alternative load paths.
Guidelines from the General Services Administration (GSA), the Department of Defense (DoD), and local building codes often mandate progressive collapse prevention for certain building types and high-risk uses. Many clients also choose to go beyond code requirements, requesting customized risk analyses to meet specific safety goals.
