No. There has never been a total collapse of a steel-frame, fire-protected high-rise building other than the three World Trade Center high-rises on 9/11.

There have, however, been partial collapses of steel-frame, fire-protected high-rise buildings around the world and a total collapse of a steel-frame high-rise building without fire protection in Iran — although AE911Truth has documented overwhelming evidence that the collapse of this building was caused by controlled demolition.

There have also been partial and total collapses of hybrid steel/reinforced concrete-frame high-rise buildings without fire protection as well as partial and total collapses of reinforced concrete-frame buildings, which typically don’t have fire insulation. There has also been a total collapse of a concrete-frame building without steel reinforcement.

Therefore, the Twin Towers and Building 7 stand alone as the only steel-frame, fire-protected high-rise buildings to experience total collapse ostensibly due to fire.
