Can someone explain building 7 collapsing?

Question

no jet fuel no plane

Answer 1

Two one hundred plus story buildings falling within a distance of a couple hundred yards just might shake the ground and foundation that all the buildings were built on just enough to knock one down. I am no architect or engineer, but this does seem to make sense to me.

Answer 2

The intense heat of the fires that were ignited by jet fuel, after the impact of planes crashing into the Twin Towers Of The World Trade Center after the collapse, the fire had spread to adjacent buildings including the original 7 World Trade Center built in 1987, which also collapsed hours after at approximately 5:20 p.m. on the evening of September 11, 2001 even in the aftermath, the ruins were still smoldering the next day.

Answer 3

It was hit with massive amounts of debris from the collapse of the North Tower, with incredible force. This caused both tremendous structural damage and fires throughout the building. As early as 2:20, firefighters evacuating the building saw signs of impending collapse. The firefighters were ordered out at 3:30. The building came down some time after 5:00.

Answer 4

It had something to do with planes knocking two really big structures down triggering a domino effect on the other buildings. I don't expect you to believe that, seeing as that is what the evidence says. But, people like you don't seem to care much for evidence anyway.

Answer 5

It sustained severe structural damage and fire caused by the collapse of two huge buildings next to it. Several other buildings in the immediate area also sustained heavy damage that day and have had to be demolished as a result.

Answer 6

both massive damage from falling debri and also massive damage to most major support column due to the collapse of both the north and south towers - it is believed that initial damage that weaked the supported columns happened when the planes hit both towers - the collision were so intense that literal screwed up under ground support and destabilized buildings.

Answer 7

I'll tell you what genius.

To put this in perspective for you:
You hold still. I'll get a piece of concrete as big as you are and drop it on you from a height of one foot.

How ya feelin'?

Now try to imagine you are a hollow building sitting on ground that just got a shock equal to a 7 on the Richter scale and that a barrage of pieces of concrete several hundred times that size are coming at you at street level over 120 miles per hour, you are full of pressurized fuel oil tanks and one of your legs just got ripped off.

Getting the picture?

Ok, now burn for seven hours.

How ya feelin'? Ready to go down yet?
Don't tell me you need help.

Answer 8

Can you save the crap for one day?

I can't imangine why a building that was less than 100 yards from two buildings that collapsed and threw hundreds of of tons of steel and concrete onto the ground below, fell.

Answer 9

Its foundation shifted due to the shake of adjacent structures.
The carcass lost its strength due to cheap design and collapsed.

The whole WTC complex was designed badly with the strength coefficient of 1.1. This is a common problem of 1960s structures, for example, that bridge over Mississippi: cheap design.

Answer 10

It was a plot by Bush, Cheney and Rumsfeld to raise oil prices so they could all get richer. Then they invaded Iraq to get the oil and get richer. They also created Katrina with a secret weather machine Condi Rice invented to get the black man out of New Orleans so they could drill for oil there and get richer. They also created the tsunami using technology stolen from aliens being held captive at area 54 that killed 200,000 people in SE Asia so they could drill for oil there and get richer.

I thought all of this was common knowledge?
