What can cause steel structures to collapse during fire conditions?

Unprotected steel columns and beams exposed to heavy fire and high heat conditions can precipitate an early collapse. Steel beams attacked by the heat of the fire causes them to expand. Failure of a beam can affect a localized area. A column failure can trigger a substantial building collapse.
