Now, if I took all the energy my house could withstand, and focused it into just one single part, say, a corner, it would not hold. Another way of explaining this. A single stand of rope on its own, is very weak. Now, take hundreds of strands and weave them together, its very strong. Now do you understand?? BTW, yes, my house has about 1500 LF of steel built into it. I am an engineer, and live in a hurricane prone area." This is what the structural engineer David Scott had to say when speaking to colleagues at the Institution of Structural Engineers in the UK. Perimeter columns designed to endure hurricanes, Scott says, were loaded only to "about 10% of their ultimate capacity" in the gentle breeze on 9/11. The Twin Towers were overbuilt to prevent office workers from getting seasick on windy days. Dennis Kollar, P.E., said "There's so much redundancy....The building has to be stiff enough so it doesn't sway." Kollar cites a claim by the Towers' engineers Worthington, Skilling, Helle & Jackson that even with all the columns on one side cut, and several around the two corners, the Tower would still withstand 100 mile-per-hour winds.
