I know I've seen this explained on TV quite a bit. You're chosing to ignore it.
The towers were designed to take hits from jet airliners on their way IN to New York... IE, having already completed their flights and carrying very little fuel.
The planes that hit the towers had just taken off and were packed to the gills with jet fuel. AS CRZYONE JUST SAID, the heat from the fire weakened the building's structure and it collapsed.
It collapsed perfectly because of gravity. There was a lot of potential energy put into those building materials when they were lifted to the top. That energy was returned when the building collapsed.
It ought to be pretty obvious from the videos that the entire cross sectional area of the building was affected by the impact of the aircraft. The columns gave way more or less at the same time and the building came down in an implosion exactly as it would have if it had been rigged with charges.
