"Are the building codes going to be changed considerably now that we have discovered that a fire can damage modern high rise structures so easily that they collapse ??" Since all the remains of the buildings were illegaly removed before any investigation into the mechanics of the collapses could begin, that's a moot question. Gee...why would all that evidence be destroyed? Did those devious hijackers arrange for that?

From what I understand, the WTC was a unique "lightweight" design with some corners cut (during construction) that made it especially vulnerable to the very type of progressive, escalating collapse that occurred after the fire(s). More conventional high rise buildings have much heavier structural steel on the interior, and would be less likely to collapse like the WTC did. pbs.org
