The Empire State Building withstood the crash of a plane, but not the Twin Towers of the World Trade Center, which happened on a Tuesday, September 11, 2001. It was truly tragic but people learn from their experiences and mistakes.
My grandfather was a postman in this building around wartime and told us he made more money in tips from grateful businesses at Christmas time than the postal salary.
Great work! I love the videos about bridges, buildings, and dams. The explanations of problem solving and construction phasing are top notch. You make me a better civil engineer.
Great video. One correction - the building getting narrower towards the top was not an aesthetic choice, it was a legal requirement. After the Equitable Building was built downtown, all skyscrapers had to have setbacks if they wanted to go higher. This was done so that the buildings would not block the sunlight from hitting the streets. More info here - en.wikipedia.org/wiki/1916_Zoning_Resolution
The zoning law states that the hypotenuse of a right triangle drawn from the opposite side of the street with a 25 degree angle or so can not touch the building which is why the building needs setbacks every few stories on the lower level. The exception to this rule is that 25% of the lot size can be built as high as technically possible. (This explains why developers buy air rights from neighboring plots.) The last setback the Empire Stare Building needed for the zoning law is at the 29th floor. The shape of the building above the 29th floor was to make 8 corner offices while using exactly 25%of the lot size. The floors above the 86th floor observatory were intended to be a mooring mast for dirigibles but the plan was put on hold and scrapped after the Hindenburg accident.

As I remember back in the 70s, they had a glass showcase with a brick in it, and if I remember right it said they had ordered either 10 million or 100 million bricks for the building and had ONE brick left over! Those terra cotta blocks used in the floors were commonly used back then in partition walls and elsewhere, they were why the gothic styled building at 90 West Street which had raging fires after 9/11/01 survived. They still use these blocks to-day in home contruction in Romania, Slovakia, Hungary, and I imagine elsewhere in Europe. I saw google street views of a new house under construction in Hungary, it used those same terra cotta blocks which were then faced with stucco, while the roof was made with red terra cotta roofing tiles. They are superior to the cheap concrete blocks we use- larger in size and having multiple cavities in them, they have more insulation value than concrete blocks, and since they were clay that was hardened and vitrified by FIRE, they stand up to a fire whereas concrete blocks crack and crumble because concrete is made into a powder by grinding up and burning limestone, adding water and sand to that chemically cures it into a hard form but it's not vitrified like terra cotta
It's a shame you didn't mention the bricks used in the foundation. They were called Accrington Nori's and they still are the strongest brick in the world. They come from Accrington in Lancashire England. There name comes from Iron being backwards on the mould by accident. They are so strong because the amount of Iron in the clay.
I really love your channel, I hope people stop watching stupid tikto videos, and spend their time learning from your channel! Love you lesics team! 💪💯🔥 Stay strong
I don't think anyone today could do what these workers have done back then. Such perfect engineering. Something not seen anymore. We give our thanks & gratitude to those hard-working Americans.
It's been said that the stepped design of the buildings is due to air rights regulations in New York city but I saw no mention of that in this video and instead it would seem that this video suggests it was a purely aesthetic choice. Please explain
Are the fondation steel column left "raw" at 7:36? It seems that the steel underneath the ground is not recovered by brick or cement . How do they protect it from the corrosion as humidity is very high undergound ? Thank you for your answer
It was built in 13 months around 90 years ago, no computer aided design, none of the technology we have today. It also was built ahead of schedule and under budget. Compare that to the 6 years with all our modern technology it took to build the new Wembley stadium, which ended up way over schedule and much over budget. How is this possible?
A building built almost 100 years ago stood up the impact of a plane, but a 110 story monster with far more advanced engineering collapsed like a house of cards in 2001? Seems legit. Right?
No, you are simply mis-informed. The plane that crashed into the Empire State Building weighed 33,500 pounds with a maximum fuel of 974 gallons of fuel traveling at a maximum of 275 mph. The 767 that hit the WTC weighed 284,000 pounds, carried 12,100 gallons of fuel and were traveling in excess of 500 mph. Spot the difference. Not being able to comprehend that makes it redundant for me to explain the difference in the construction of the 2 buildings.
Can you provide or give a reasonable guess on the structural load for the red brick exterior and interior core of this building? I am confused as to how they built this skyscraper using red brick core?

The amazing thing is the lack of comments with the obvious observation that the World Trade Centers could not have fallen at free-fall speed because of an airplane crash, given their improved structural rigidity over the ESB
Improved rigidity? Look at the structure of the ESB in this video and compare it to the WTC. Likewise consider how the I beam and clay pot floor would stand up against fire compared to the WTC steel truss design (aside from differences between plane crashes).
One thing that I noticed on some old film about the construction of the empire state building was how to achieve the required precision that all the steel beams and girders. After all the plates were riveted together, this would leave both ends rough and uneven, the iron workers would run these assembles through a giant milling machine that would shave both ends to a square and determined length. By making these all square and the same over all length, they could easily take them to the building site and put in the main assembly of the building without much drama to get things to line up. The brief moment in the movie clip that had this milling machine, showed it must have been huge. There was one of these Carnegie beams mounted in the machine and the two cutters on either end were both turning. These cutters looked to be about six feet in diameter and the bed of the machine must have been about 50 feet in length. I am curious, is that how big i beams are made, no rivets, all welded. But do they still shave the ends to maintain the length and squared ends?

You have one correction to make. Ironworkers assembled building by driving hot rivets. High strength bolts weren't used for several more decades.
High strength bolts made their debut in the early 60s. Temporary soft bolts were used to connect members for the riveters to follow.

dont believe this garbage lie about 13 months .... you know its impossible , plus there is NO foto or video evidence of construction

These cutters looked to be about six feet in diameter and the bed of the machine must have been about 50 feet in length.
I am curious, is that how big i beams are made, no rivets, all welded. But do they still shave the ends to maintain the length and squared ends?
That plane was much smaller and lower on fuel.
Finally sir you upload video, i am waiting for a long time ☺️☺️
Meanwhile the Twin Towers 💀
💀
That was incredible!
Fun fact: zero feminists were used during the construction of this structure
It might not be fun for you but at this point you are more obnoxious than those feminists
🎯 Key Takeaways for quick navigation:
00:00 En *1945, un avión bombardero chocó accidentalmente con el Empire State Building, pero la estructura resistió, revelando su increíble resistencia.*
00:41 La *construcción del edificio implicó el trabajo duro de los "Sky Boys", trabajadores del acero que realizaron la impresionante estructura de acero a 443 metros de altura.*
01:48 Para *alinear verticalmente las columnas de acero, utilizaron un ingenioso truco con cuerdas antes de remacharlas en su lugar.*
03:12 El *diseño del Empire State Building se inspiró en un lápiz para dar la apariencia de altura, manteniendo el mismo ancho desde el piso 29 hasta el 71.*
04:08 Originalmente *planeado como un edificio de 50 pisos, se modificó 15 veces durante la construcción para competir con el Chrysler Building, alcanzando finalmente 102 pisos.*
05:47 La *construcción rápida se logró mediante la planificación precisa de estructuras prefabricadas y la ejecución simultánea de múltiples actividades de construcción.*
07:25 Para *superar el desafío de los elevadores, se dividió el sistema en siete partes, ocupando una gran parte del espacio del piso.*
08:23 A *pesar del impacto de un avión en 1945, el Empire State Building demostró su fortaleza al reabrir después de solo una semana de reparaciones.*

Nah it stood strong because jet fuel can’t melt steel beams
Amazing spectacular engineering. ✌️
Remember when two planes took down three buildings

Amo o lesics força o canal vai em frente
Very glad to see your videos
The secret is not having charged explosives and weakened beams and needing to enter a profitable war
Trying to tickle the algorithm, awesome video man!
What about World Trade Center 😂
