Actually multiple inpections by different bodies were conducted prior to the 9/11 disaster. There were fireproofing upgrades, elevator system upgrades, and other renovations going on.
We can't piece together anything because the debris was shipped off, the evidence was destroyed.
When any plane crash or other disaster (think Lockerbie) involving airframes occur, they literally put the plane back together piece by piece to reconstruct what happened. They also use the black boxes of course, but these were also not used because for the first time in history they weren't found.
The building materials would have helped a building performance investigation, but FEMA weren't allowed to claim any materials - which were trucked away from the scene under guard.

In these cases, the buildings collapsed because at some point the a section of the building was unable to support the weight above it. Once one floor falls, it falls down, and once a floor falls all of the floors above it come down too.
How can you not see this?
|
In one case you had 70% of the building being pile-driven to dust and sectioned by the top 20%.
In the other you have 80 to 90% of the structure being crushed by a top section of 10% the building mass.
In both you have a complete violation of physical principles.

Call it whatever you want. I've never seen the word "softened" used in this context by the NIST. Either way it was weakened. If you put a five hundred ton load on a steel beam and subject it to six hundred degrees for an hour, guess what - It's gonna be weakened.
|
If your steel beam is structured to withstand the load, no. And it would take more than 600 degrees (F) more than one hour to weaken the beam.

With the WTC towers, yes, the building was designed so that it could survive a fire. However, it was not design to withstand a fire that was started by ten thousand gallons of jet fuel. It was also not designed to withstand a fire after an impact.
|
By NIST's account about 7000 gallons were distributed unignited within either building, give or take. The rest exploded on impact or outside the building.
The buildings were designed to withstand both impacts and fires, and both were taken into consideration by the designers of the buildings.

But nothing here was normal. This was not a "building" - it was one of the world's tallest skyscrapers.. Two of them in fact.
|
These facts don't exempt the buildings from the laws of physics, no matter how big they are, and nothing in any normal or abnormal fire, inferno, conflagration could create molten steel in such amounts and foundry conditions that it would take weeks and months for it to cool.

|
The gennies and diesel they held were dismissed as any factor. NIST even stated that in the worst case scenario this fuel igniting, exploding and burning wouldn't have created enough heat to weaken the structure.

|
"must have" and did are two different things. UPS battery acid won't weaken steel or burn for weeks, and I don't care how many cars you count they won't have been turned to liquid by a burning building collapsing on them, a collapse which in fact would have snuffed out most fires within the structure as it fell.

Where do you get that took out anything? The pipes here connected to the outside of the buildings, where window washers could access it. They hooked up their tubes to connections on the outside of the buildings. It became the greatest week point, and when that fluid was forced out, it came out at the weakest point.
|
And blew steel columns and aluminum cladding to pieces, and concrete to dust??

No, it doesn't. It shows air and other fluids being compressed out of a building.
The only reason you think this is because the only videos you've seen of buildings collapsing were intentionally done. This looks similar. Doesn't mean it's the same.
|
No, I'm talking about actual WTC tower destruction video.

No. Stop making shit up. Steel melts at about 2500f. But it's weakened at at less than half that. The estimated temperature of the fires in the WTC was 1340f - more than enough to weaken it.
|
I don't know where you get your figures but it's not from NIST or FEMA.
And steel takes hours at the right temperatures to approach the softening or weakening point as well as its melting point - it does not instantly convert once those temperatures are reached.

Where do you think they used Thermite?

As I said, I don't know that it was used in the construction of WTC. And I don't think that thirty or forty years later it would be in the pulverized concrete of the destruction - at least, not unexploded thermite and military grade thermate; I'm sure different thermite is used. But again, it's not established that it was used or stockpiled...
