Why did the wtc buildings fall with no resistance?

Question

By looking at the Blueprints of the buildings they should have fallen into the street. It looks impossible to have panaked so to speak.

Answer 1

Get the tin-foil off your head and watch some of the documentaries that discuss the structural failure of the buildings due to the terroristic attacks.

Answer 2

The heat from the jet fuel was so hot it softened the steel causing it to fold.

Answer 3

By WHO's looking at the blueprints?????

Anybody can look. For the actual  designers of the building,

that type of pancake collapse was a 'worry scenario'

in the discussion of the insulation of the structural steel,

(Substituionof the new insulation for asbestos),

before the things were even built.

"Who ya gonna believe?"

Answer 4

They collapsed because the heat of the jet fuel burned the steel holding them up.  I'm not sure what you mean by no resistance.  A plane slammed into them.

Are you asking why they didn't tip over?  Because the planes flew into the upper floors, so the weight of those caused them to fall on the lower floors, collapsing them in a domino effect.  Ever play Jenga?  Same principle.

Answer 5

Huh? How would they fall outward? The DESIGN was for inward-collapsing and pancaking to begin with!! This is done for all of these types of buildings for wind and seismic resistances.

The elevator shafts, also called the 'inner-flagpole' were specifically designed with stronger materials and weight than the exterior walls, also called the 'curtain-walls'. The floors connected to both the heavier/stronger 'inner flagpole' and the lighter/weaker 'curtain-walls' (in comparison to the flagpoles). When the buildings were penetrated and sheared from the planes, and the hot fires from the burning jetfuels forced the steel floor trusses to bend, their end-connecting bolts sheared off/popped-out, which caused the exterior walls to fall inward, towards the elevator shafts. The floors then separated from their end-connections, and started falling on top of other floors, which was the pancaking. The 'curtain-walls' fell slower than the floors, the floors fell faster than the 'inner-flagpoles', and the 'curtain-walls' fell into and on top of the floors. The 'flagpoles' tumbled down last. Basic Physics.

The resistance friction of the steel sliding down the concrete 'flagpoles' and rubbing other steel materials caused the molten steel fires after the collapses.

Answer 6

it looks like a controlled demolition
