WTC tower, what if it did not collapse?

I am not a structural engineer, but I’d guess that the horizontal shear strength (if I am using the right term) of the towers was nowhere near as strong as their vertical load-bearing capacity. The enormous weight of the towers could be supported only vertically – they were not rigid enough to behave like a tree trunk. If you tried to tip them over sideways, they would not remain intact and tilt, but crumble as they started to tilt – as the top part got displaced from the vertical, the load bearing structures would break – and they would and come almost straight down anyway.

Excellent, and correct explanation! Well done.
