Remember too that when the collapse started in any of the buildings, even if initially small, the load changes from static to dynamic load. That is a different color of a horse. As soon as floors start collapsing, you have a series of dynamic impulses which likely exceed the design dynamic load very quickly.

Box-shaped structures are also inherently weaker structures than things like domes. Forces tend to concentrate at load points rather than being distributed through the overall structure, sometimes even balancing themselves, like trying to crush an eggshell with uniform pressure. Weaken the structure at those load points and overall collapse can follow fairly quickly.

Plus, who knows what might have been stored in all of those buildings and what materials were used. Medical offices, labs, the malls with shops...what a stew of germs and chems, Hazmat central. The truther nuts are always saying “how come everyone got sick?” disregarding the HUNDREDS of pictures literally coated in who knows what for hours. A lot of the clean up guys refused to wear masks, too. The chiefs were constantly telling them to put masks on. They were hot and cut down on vision. Seemed like a good idea at the time.
