FEMA's Report Misrepresents the Tower's Construction

The towers were designed to withstand 140 mph winds, in which event the floor diaphragms would help transfer lateral loads between perimeter walls and core. Absent such loads, the structural function of the floors was not in play.

Yet FEMA's report pretends the towers would instantly self-destruct if the floors fell away.

Key to this deception is hiding the strength of the core structures.

• Core column cross-sections are shown about 1/3rd their actual dimensions.
• Cross-bracing core beams are not shown.
