If the first 5 floors colapsed, would the weight of the building cause it to come straight down? Or would there be a momentary pause, as the steel structure got bent and concrete broke apart? There just doesn't seem to be any resistance as it is falling down.

And that is very confusing. Had the building slowly collapsed, I wouldn't have thought twice about it. It collapsed at free fall speed, which is impossible for a steel framed building (except when the steel supports lose all strength at once, whihc is not supported by claims that the building fell due to fire and minor damage from debris).
