My father, an almost retired engineer, would absolutely agree with you.

Actually the original design with the flaw was down to the chief engineer. And it was an architecture student who called him and asked about the flaw.

Doesn’t even look cool, that’s one of the dumbest designs for the base of a building I think I’ve ever seen, actual fucking worms for brains.

The design of the stilts wasn't the problem; it's that they riveted/bolted the girders together instead of welding them, allowing too much movement in the tower. This video was poorly researched.

​​@@yuioyup You mean ... why do people make changes to a structural concept without asking the structural engineer first? Savage. But not in a good way.

@@neatwheat That too, of course! Just as importantly, once that disastrous oversight was made, denying hundreds of thousands of people the right to make an informed decision on behalf of their own safety is also problematic, and the “always lying” part they were referring to. Those people had a right to know what was going on, and choose to stay away or come in and work anyway. They were lucky it worked out but it could’ve easily gone awry.

​@@yuioyup$$$$$$$$$$$$, really.

Exactly

The key failure was in the analysis of the fastening change. They analyzed the building for wind loading but only looked at face wind loads which are usually the worst case for square buildings. With this unique design the cornering wind load was the worst case condition. So while the change was fine for face winds, it wasn't for cornering winds.

They used rivets instead of the bolts required by the plans.

i think he said inquiring

a student was looking at the as built structure vs the original plan and inquired about the change which is how it got caught the student didn’t fix it

Diane Lee Hartley. She was a student at Princeton at the time.

Tradition is an illusion

Communists / Marxists hate beauty that’s why we have all this ugly, brutalist architecture.

nah, people think they want an all traditional architecture skyline but they don't, it gets gaudy and overcomplicated quick, also postmodernism executes the wedding cake form/ setback as you go up form of the skyscraper much better, the modernism and postmodernism is as much as part of city character as traditional designs, if you really cant handle a building being more simplistic than its neighbor then don't look at architecture, people also want to act like old architecture is objecitevly better yet if that were true then the ppg palace wouldn't be talked about more than the cathedral of learning or chicagos old buildings wouldn't be taking side seats to the sears tower and john hancock center, Except it is like that, funny huh? maybe you should just tolerate something you don't like that isint actually as harmful as you want to believe it is, almost every argument for puritisiam from traditionalists AND modernists (form follows function is a bunch of bullshit, minimalist midcentury design is cool but a lot of reasons for it were bullshit and sometimes racist) and it follows the same style of arguments made for the objectivity of music/art/movies/games people want their taste to be objectively true, its part of being human, also they wouldn't have torn down everything before 1950 like they did in the 60s in america if these buildings were so objectively better

Which is ultimately good however now that those styles along with contemporary have become the defacto default for new buildings they represent the exact opposite... conformity. And now ornamentalism and organic structures are rebellious.

Your comment made me think how often statistics and facts can be used falsely and I'm glad you said it

im not surprised. but what happens in that one in 50 year event? a second nein eleven?

Not really. Simulation analysis was done and quaternary winds actually produce less wind pressure on the building.

​@@Repleh yeah, but the contractor didn't use the same stuff the engineer intended

@@revolvency - NIST - which did the simulation analysis mentioned by Repleh - recommended reanalyzing the building structure to see if it had adequate strength - since NIST determined that the NYC code was adequate to withstand high winds - it's likely that even with the bolts (replacing welds) - the building would probably not have collapsed the chief engineer LeMessurier never spoke with Diane Hartley who had warned of quartering wind loads - it was his phone call with student Lee DeCarolis that prompted him to recalc the wind loads - and after comparing them to the building's construction - determined that it could collapse if the electricity was cut and disabled the dampers used to control the building's sway - so he reinforced it - - but the NIST reanalysis suggests it may have been unnecessary

Imagine if that student didn’t believe in themselves… It would’ve been very easy to look at that huge billion dollar building, look at all the well respected architecture and engineering firms involved, look at all the senior engineers and tradesmen, and say to yourself “Surely they can’t _ALL_ have missed this, I’m just a student. They know much more than me, I’m probably the one whose wrong.”

1993

IIRC there were two issues. The wind direction issue is what the student figured out, but it wouldn't have necessarily caused a collapse. It did mean the margins were much smaller than the engineers had believed, so they decided to review everything. That's when they discovered the second issue: a contractor had swapped out one type of fastener for another, which made the building's unusual structure too rigid. The two issues combined dropped the safety margins for lower than is acceptable.

And contractor approve the design

Something like "I can't understand what keeps the building to collapse in winds like this" "... Oh shit, you are right, nothing"

Diane Hartley's calculations determined that quartering winds would be high enuf to collapse the building - made weaker by the placement of the columns chief engineer LeMessurier (who never spoke with Hartley) recalced the wind loads after a phone call with another architectural student Lee DeCarolis - and thought they could be a danger if the electricity goes out - causing the damper system that reduces the building's sway to stop - he then learned that critical braces in the building were joined by bolts rather than welded - and he thought that the NYC code which the building met was inadequate - so he instituted the reinforcement ironically - recently NIST has reanalyzed the wind loads using modern technology - and found the wind loads were not a problem - and that meeting the NYC code was sufficient - they recommended a reanalysis of the original design to determine if it needed to be reinforced after all in short - both Hartley and LeMessurier were wrong about the wind loads - there was likely no danger of the building toppling

​@@johneyon5257better safe than be sorry, ig But thanks

afaik the student was like "I can't see anything wrong with my calculations, what did they do that I missed?" and the engineer was like "well, fuck she didn't miss anything."

And the teacher was willing to loose his livelyhood by admitting he built an unstable skyscraper. There was a very real threat that he could have been screwed. Luckily engineers are decently intelligent so they praised him for it to encourage people self reporting issues instead of hiding mistakes. Nowadays we call that a blameless culture and it's commonly used in aviation, architecture, infrastructure etc

Humble? More like terrified lol, if that thing had collapsed his life would have been ruined

@@Viki1999you guys have the story all wrong. The architect of the building is LeMessurier, and he wasn’t a teacher. It was a Princeton student that discovered the structural flaw and informed her professor, who in turn informed LeMessurier’s firm. He assured them the calculations were correct until a second student later called him up and convinced him to check on his calculations.

@@AndorranStairwayYou have most of it. Just missing the correct ending. The plans and calculations were 100% correct. However the engineer checked the final plans anyway and noticed the contractor had made last minute changes with the material used which altered the calculations and made it unsafe because of the weight and type of screw/weld used. So he wasn’t wrong, the contractor was by not having anyone recheck for the new accurate measurements. So really the engineer and that student were both hero’s! But yeah no one ever gets this story correct.

@@Repleh - Diane Hartley never spoke with LeMessurier - she spoke with an engineer at the NYC office while LeMessurier was in his office near Boston architectural student Lee DeCarolis spoke with LeMessurier via phone - he simply asked questions - but that got LeMessurier to recalc the wind loads - and his calcs determined that if the electricity failed and the building's damper failed - the bracing might not hold the building together due to bolts replacing the welding originally planned NIST reanalysis has determined that LeMessurier's recalc was wrong - that the wind loads would not have been as severe as his calcs said - they recommend a reanalysis of the building structure to determine if the expensive reinforcement was even necessary

They replaced the welds with bolts because it’s a lot easier to construct. LeMessurier only found out later when he was working with the same contractor on a later project, and they asked if they would also be able to do the same swap.

the student was Lee DeCarolis - his talk with LeMessurier prompted LeMessurier to recalc the wind loads - and the building's ability to withstand them - and he determined that IF the building's dampers were stopped due to electrical failure - then the structure might fail - due to bolts being used to hold together the V bracing that directed the weight to the beams - instead of the welding that was planned for now we have the technology to measure wind loads - and LeMessurier was wrong in his recalculations - the wind loads were less severe than he (and a woman student named Diane Hartley) thought - there was likely no threat of collapse at any time

Poopin?

Then dresses it in a bow tie and names it bob the pooper 😂

a NIST reanalysis using modern technology - says the wind loads weren't the danger that they thought back then - the building may not have needed to be reinforced at all

no need - the engineers solution worked fine - the issue of a collapse in high winds is probably a chimera - using modern technology - it's been determined that the wind loads weren't the threat that was thought 40 years ago - the building may not even have needed reinforcement

not by engineers

it was probably more than safe since it was reinforced - a NIST study determined the wind loads weren't going to be as bad as thought - and the reinforcement may not have been necessary
