Safety Factor Explanation for High Rise Towers & multi-story buildings Like the Twin Towers & WTC-7, showing 7 Cubes of 16 Floors each and approximate Steel Thicknesses with Elevation

This Poster explains what a Tower of building's Safety Factor and Collapse Efficience is. The building, as a whole, has a Safety Factor, but also each floor can be expressed as having it own Safety Factor and Collapse Efficiency.

Collapse Efficiency is simply the Collapse Load devided by the Live Load, that is to say how many multiples of its own gravity based weight can it support, top-loaded, before collapse may possibly ensue.
