Citigroup Centre in Midtown Manhattan He is also known for his speech, 601 Lexington Avenue. There, the median New Yorker has stood for 47 years, longer than it was alive. It’s still a rather handsome building, but now it leaps gently into the skyline in a way that portrayed the 70s. However, at the street level, the building continues to turn its heads. It is arranged in a series of stilt rows It is placed in the middle of the wall, not in the corner. Visitors who have no knowledge of structural engineering passing through Citigroup Centres may wonder why it doesn’t fall. This was a really serious concern for the months of 1978.
This story is told with a special explanatory vividness The new Veritasium video aboveusually starts with a phone call. Obtained by an unidentified architectural student William LemeslierCiticorp Center’s structural engineers express their concerns to relay what he had heard of as he was known at the time, about his ability to withstand a “quarter wind” and withstand a “quarter wind.” Lemessurier spent time roaming his students about elements of his time-based ground lightweight design, including a chevron-shaped brace that had tension loaded up a pillar, and a chevron-shaped brace that guided a 400-ton concrete tut damper (or “big blocks of cheese”) intended for oscillating motion movement.
Lemessurier was a proud expert, but his professionalism surpassed his pride. He was left with an unpleasant surprise when he returned to check out the plans for the Citicorp Center. The construction company replaced the welded joints of those chevron braces with cheaper bolted braces. His office approves changes that made sense at the time, and, like standard industry practices at the time, only considers vertical winds, not a quarter of the wind. Performing the related calculations himself, he decided that he could defeat the entire tower – and in the surrounding area that was destroyed by it, he destroyed it by winds that could blow 16 in 16 people.
All he could do was reveal what he had discovered at Citycorp. That leadership could only reveal what he had discovered to Citicorp, who collaborated on the accelerated semi-Crandistin project, which reinforced the structural joints of the sparkling emblems at night. Of course, the film could hardly attract the attention of the New York press, but it received a small amount of coverage thanks to a perfectly timed newspaper strike. In fact, the story of the City Corp Center disaster that was not only publicly appeared 1995 New Yorker Works by Joseph Morgensternmade Lemessurier a kind of hero among structural engineers. However, it was the students who identified the building’s mistakes, and then not only one but two people came forward, personifying the life-saving power of asking the right questions.
