You're either disingenuous or dumb af.
Why the anger? I've been polite and factually accurate. What more could you ask for?
Still holding a grudge because I pointed out you're an illegal anchor baby?
does not lose any significant strength at temps anywhere near those experienced in a building fire,
Not only is this not true, but several people conducted tests, with structural I-beams (are the i-beams which are not structural?), to show it is not true. This is basic metallurgy.
Additionally, videos of formal retardant tests clearly show your statement is wholesale false. These were widely watched at the time.
The idea that a few joints here and there
That's your unsubstantiated contention. And is contrary to general understanding of the fire. Especially for all steel near the elevator shafts.
Your anger is misplaced and undeserved. As I said, you destroy your own position.
The retardant is a critical requirement for building code. Without, it is not considered structurally safe against fire. Period. This is in fact why the building was sold. While I no longer remember the cost associated with replacement (billion?), it is considered the primary reason for their insurance scam. The previous owners were losing insurance because it was not safe for occupancy without the retardant. The sale reset that and it became a condition of coverage.
It's mind blowing to me that you won't even consider the most likely truth. That collapse was much easier to create specifically because of the reason they would lose insurance coverage and required massive expense to mitigate.
But I guess sticking with the facts makes me a shill...
I seriously don't know why you're angry here.
You are not even remotely factually accurate. About as accurate as describing me an an illegal alien.
"Structural steel" is a classification of steel required by code to be used to build steel frame buildings. The speculation is specifically chosen for resistance to fire re minimal expansion and strength maintenance in temps associated with building fires. Read the fucking code requirements for structural steel. Hours at temps over 2000F under full rated load with no deformities.
Thousands of architects and engineers have called bullshit on the pancake theory of collapse and have put their names, licensees, and reputations on the line making that determination.
Fire retardant on columns is not put there to prevent steel beams from collapsing in a fire. That's fucking stupid. It is used to lower the cost of recovery following a building fire. Within the parameters of the retardant, far less testing and repair is required if it can be shown that the fire retardant limited the exposure to the steel.
Again, with or without retardant, steel framed buildings do not collapse symmetrically, near free fall speed, because fire. Never happened. Never will.
You goal post move well past what I stated. You also continue to push lies while avoiding what I actually stated. That pretty well sums up the exchange.
Have a good day. Hopefully Mexico welcomes you back.
You are full of shit. I did not move any goal posts. I have stated nothing that is untrue. And I have addressed your points.
You said that steel, when heated, loses its strength. I addressed this exact point. Structural steel does not lose any significant amount of strength when heated to temperatures associated with building fires. It is one of the design criteria behind the establishment of the term structural steel and the very reason why structural steel is required by code to be used when building steel frame buildings.
You then suggested that when steel is heated it expands and that this thermal expansion caused joints to fracture. I addressed this point as well. Another design criteria of structural steel is minimal thermal expansion when dealing with temperatures commonly associated with building fires. It is another design criteria that is used to establish structural steel as the requirement, by code, for building steel frame buildings.
The very selection of the material used to build a steel framed building is based around the temperatures commonly associated with building fires so that the structural steel will not lose integrity and will not fail resulting in the collapse of that building. This very fucking thing is the exact fucking reason why no other steel frame building built in modern times in the United States has ever collapsed as a result of a fire.
You suggested that fire retardant is used to prevent a steel building from collapsing from a fire and that this retardant was missing. I addressed this point. It's fucking stupid to believe that they put fire retardant on steel beams to prevent the beams from weakening and causing a building collapse. Given that a steel-framed building in the United States, built in modern times, has never collapsed, it would seem fucking retarded to take the additional step of trying to use additional materials to prevent something that is never fucking happen. I then went on to explain that fire retardant is used to minimize the cost and to mitigate the effort needed to restore a building that had been involved in a building fire to normal working order. It is far more cost-effective to put something on a steel beam that would prevent the beam from reaching temperatures that would then require post fire ndi testing and post-fire repair.
And finally, I addressed the idiot fucking theory that this building or any other building at the World Trade Center collapsed in pancake fashion. There is absolutely no possible way that floors can collapse upon each other with the lower floors still maintaining structural integrity (the building was never engulfed in flame) and have that collapse happened both symmetrically and at a near free-fall speed rate.
You then suggested that "experts" disagreed with me. Experts of the caliber that suggest wearing paper masks are effective in reducing the spread of covid in.a, pandemic, I'm sure. But there are literally thousands of actual named, degrees, licensed, and practising architects and engineers that have gone on record to record their objection to the implications made by the assumption that these buildings collapsed in a pancake fashion. No fucking way.
I posted no lies, addressed your points, and moved no goal posts.
