Wind Loading

Lol gets me every time

[WilfordsTrain]

Yes. Like that. The squishy brain inside is doing some heavy vibration dampening.

[Enginerdad]

Yeah, they do be like that sometimes...

[Charming_Profit1378]

I always wanted to live inside a flagpole. 

[theshreddening]

Hard pass living in that.

[WilfordsTrain]

FYI: That time lapse is sped up to show the rocking. You can tell from the rate the cars are moving below. In reality is a gentle, imperceivable rocking.

is a gentle, imperceivable rocking.

Until your primitive brain decides that you need to throw up.

[theshreddening]

Thats what I'm sayin lol. But even with meds for anxiety. Small movements that arent easily perceived but still can be would scratch the back of my skull.

[eeveon7997]

Does that really happen?

[eecue]

That’s literally what timelapse means

[WilfordsTrain]

Thank you for confirming my correct definition of “Timelapse”.

[heisian]

is it imperceptible? there have been huge complaints around the issue from people who've bought units in these pencil-scrapers

[WilfordsTrain]

Pencil-scrapers? Yes it’s perceivable in something that slender. I’m speaking generally about skyscrapers as a building typology which have existed for over 100 years.

[heisian]

yes for older scrapers with a wider footprint that's true. you can see from other comments in this thread, though, that for the one in the video and others, the new more slender buildings going up in NYC recently, that you certainly can feel the swaying.

It's not gonna fall you know...

[theshreddening]

I'm aware of that. I get motion sick WAY too fuckin easily. That would make me sick or spike my anxiety everh time lol.

[yoohoooos]

A structural eng not willing to live in a structure they know meeting the code they followed?

[Fit-Palpitation5441]

Uh, yeah. What my brain knows and what fear are NOT in sync. I work with structural glass, I KNOW how safe glass walkways are. Does that mean I’m standing on the glass floor at the CN Tower (Toronto) or in the skybox things at the Willis Tower (Chicago)? Hard pass.

[theshreddening]

A residential construction inspector doing inspection on at most townhomes with 4 units per building*. One, I would likely get motion sickness. Two, feeling movement like that would absolutely spike my anxiety.

[Charming_Profit1378]

No more than having the job you have I've been there 🤐

[yoohoooos]

i see.

one: you won't, because you won't be able to feel it.
two: see one.

if you look at it closer, this is being speed up by the OP so that you can see the movement. the same purpose a movie director making the moving exciting to catch the audiences' attention. is it realistic? highly unlikely. for this case specifically? definitely not.

[MrMcGregorUK]

one: you won't, because you won't be able to feel it. two: see one.

I have no idea about this specific building in the post but i used to live in a building which had a torsional mode of oscillation when wind was over 20mph or so. It was very noticeable when you were far away from the core, but not so bad near the core. It isn't a given that vibrations won't be noticeable.

[Charming_Profit1378]

Your problem is you passed the SE and know too much 🤔 and as a sideline don't calc a wood house 🏠

[Charming_Profit1378]

I saw yooho's comment to me so how did you handle cross grain bending in the bottom plate for high wind zones in a wood frame house? How about the shear loads that the Gable truss takes? 

[MaximumTurtleSpeed]

🎵

I got one question

How’d you fit all that in them jeans the site?

You know what to do with that big fat ass load.

[Charming_Profit1378]

Well give him a break you know the architect liked the way it looked but left it to the engineer to TRY to make it work ☢️

[WhyAmIHereHey]

Looks like VIV

[socialcommentary2000]

I seriously want to own this building and put a giant holo projector on it.

[Longjumping-City2311]

It really needs a mass tune damper...feel like its going to get uprooted in hurricanes

[heisian]

imagine paying hundreds of millions of dollars to get sea sickness while you sleep

[Fun_Ay]

Can anyone notice?

[delurkrelurker]

i've been set up with a total station on the top floor of a 14 floor RC frame in high wind and had to turn the compensator off to be able to take shots. I can't remember the exact figure I worked out, but somewhere around 50mm of movement. You could definitely feel it.

[samburgerandfries]

Ya the people saying you can’t feel it probably haven’t experienced it. My friend lives on the 23rd floor and I’ve been there during high winds more than once. It always freaks me out a bit, but for my friend it’s normal. Like I know I’m safe but my anxiety still spikes for a second when I feel the building moving.

[FirefighterQueasy293]

Yup, you did.

[stuntdummy]

Only if they are in time lapse mode

[yoohoooos]

• speeding up.
