World Trade Center changed the way skyscrapers are constructed today.
The construction of the first World Trade Center complex in New York City was conceived as an urban renewal project to help revitalize Lower Manhattan spearheaded by David Rockefeller.

However the plane that struck the towers were modern 767s with were 20% larger and traveling at more than twice the speed.

You realize there’s space in between each of the steel beams right? Planes are hollow and will dissipate into tiny fragments upon an impact like that then go out the window of the other side of the building. The plane didn’t go through beams. Plus, the beams get thinner as they got higher on the building since there was less load the higher they went. This made the building much lighter at the top than putting beams the same size from top to bottom.

[@MadPuffinMan]

And aluminum cans took those out. Still don't know how people think a aircraft punched through steel like paper blows my mind.

[@Alan-jx7uk]

Jet aircraft are made of a lot of different materials. Jet engines have a lot of titanium and other heavy metals. The landing gear is made of high strength steel alloys. The structure of the plane is made of an aluminum alloy that is many times stronger than the equivalent weight of steel. The video of the second plane hitting the second tower shows debris coming out of the opposite side of the building. The structure of the building is designed to hold up the weight of the building under normal temperatures. The high winds and the fuel from the aircraft combine to produce a very high temperature. (do research on how a foundry works) It doesn't have to melt the metal but just soften it. When the beams can no longer support the weight of the structure above it, the upper part of the structure acts like a battering ram and crushes everything below it and consumes itself as it goes down. If each piece of the structure weighs 50 tons imagine how much weight each piece is holding up! The metal wouldn't have to get very hot before it looses it's integrity and wouldn't be able to support the 1,000's of tons of steel, concrete other building materials, office equipment and people above it. It's just physics!!

Furthermore, the wings of aircraft are constructed with one or more spars running the entire length of the wing that gives them extra strength. Unless there are preexisting cracks in these wing spars, they will not be shorn off by the force of the nose impacting the building.

[@JoshBeards]

@Noelsterrr Did you know you're 100% full of it? A 767 will not "rip apart" traveling at "full speed" that close to sea level. Both planes were not traveling at "full speed" when they struck the towers, so the argument is moot.

[@michaelversant8401]

And yet somehow fire for the first time in history made both of these steel building collapse in their own footprint. And lets not forget about building 7, think the wind made that one free fall in its own footprint. What a crazy world we live on.

[@mtzak3511]

Not just fires made them collapse, structural damage from the plane crashes themselves. And no, the steel didn't melt either. But the remaining steel beams left over from the damaged area from the impact location. Those beams, exterior and core column beams were taking on some extreme heat from the fires. Not melting, but enough to warp and slowly bend the steal. The floors started to sag, causing a inward pull of the exterior columns triggering a collapse. And why it was a full collapse and not a partial, was because those towers didn't have any columns on any floors. Only the exterior (which is why the windows were so thin) and the interior core columns, for utility, elevators/stairs, etc. And each floor truss was connected from the exterior to the core columns. So when the collapse started, this allowed the floors to hit one after the other, breaking away from the exterior and core of the building, over and over. No beams to stop it, and once it hit free fall speed, there was no stopping it. And building 7, people tend to forget how close thay building was to the north tower. Building 7 didn't only suffer fire damage that day. But also an insane amount of structural damage as well, from the collapse of the North tower. Building 7 was bombarded by debris when the north tower came down. There was a gash from the roof going down to the lobby, and the lower you got, the worse the damage was on the south face of building 7. Not to mention building 7 had 47 floors, so that's alot of structural damage. And to add that fires were also breaking out uncontrollably on the lowers floors adding to the weakening of the structure. Not melting, but weakening, warping, bending.

To speak as if you actually know something. You do understand that steel can become soft well within speck of jet fuel and an office fire. Not to mention the building was already physically damaged from the impact. Which severed most of the supports. So fire softening compromised steel can and did do the building in.

wrong steel melts at 2000degree+heat its not tge melting point the reason its the strentgh and mallibilty of metal you can bend/shape hot metal thus the weight bended the metal till gravity took over now the straight down effect is another science project.

[@__ASAAA]

the fema report on the matter never states that the steel melted, the floor slabs expanded and caused stress on the vertical columns, as they got hotter and began to sag reversing the force caused by the initial expansion. eventually a large portion somewhere in the building collapsed as a result of the heat and caused a chain reaction as the floors began falling on each other. the total energy of the floors above the site of impact on wtc1 was 8x10^9 joules, all of that energy was then released on the remaining floors and caused the floors to collapse on each other and accelerate as they got closer to the bottom. thankfully nearly everyone who was in the buildings bellow the impacts was able to evacuate. sadly only 18 of the people above the impact on one of the buildings made it out, it is believed that more found the intact stairwell but were not able to get out of the building before the collapse. a few minutes before the collapse the stairwells were reported to be "relatively clear" i dont know if the remark was in reference to people or not though.

[@blueyedevil3479]

@@archsciontrismegistus4194WRONG …. STEEL has a melting point NOT at 2,000 degrees Fahrenheit, but roughly 2,700 degrees Fahrenheit. At room temp and pressure Jet Fuel burns at around 1500 degrees Fahrenheit. There’s NOTHING in ANY office building that burns hot enough independently to MELT steel. Until 9/11/01 there HAD NEVER BEEN A STEEL AND CONCRETE HIGHRISE STRUCTURE EVER COLLAPSE DUE TO ANY FIRE. ON THAT DAY THREE “BURNED TO THE POINT OF COLLAPSE” Never happened before and never happened again. There’s even been a highrise building fire that lasted for over 19 hours and not collpase… But even to your comment about the weight bending the steel… that is what should have happened, if nothing else. However, if the steel had bent, it is impossible for a vertical free fall into their own footprints. Also, the kinetic energy would NEVER be enough to collapse each floor down onto the other in one full floor… they weren’t designed nor built that way to have allowed that to happen.
