Whoever told you the steel beams expand by 55 inches is certifiably a lunatic. Whoever told you steel expands even 1% is nuts. I hope you don't think 55 inches is 1% of the beam length in a WTC tower. Remember they only ran from the central core to the outer walls.
Bigger problem is that the walls moved inward that far... not outward.
So how in heck did the walls contract 55 inches if they never expanded in the first place? If the walls expanded 55 inches (completely impossible but lets pretend) they can only contract back that far.
The posts i reply to are now gone so you'll have to guess what was said.
