[JAE]

Caught on video. Too much rhythmic pounding I think:

Take the max dead load and turn that into a live load. Makes me not trust wood truss construction.

That appeared to be a large party inside a single dorm room. To the point that it was shoulder to shoulder space almost.

That room would've been designed for 40psf. Don't fault the wood construction because it was significantly overloaded. Would you design a commercial bar floor for 40 psf? I hope not.

 

[dik]

If considered a bedroom... LL may even have been 30 psf...

jayrod12 - but, but, but....most of them were definitely floating on the clouds so the load probably wasn't that much right?

JAE: Don't try to cloud the issue here.

Oh, and there was an additional pounding effect here, from the beers.

Not to mention that a few took the invitation to drop in way too literally.

In all seriousness though, I wonder why the floor below did not fail too with 9 feet of drop? Slab-on-grade?

If they managed to hit a resonance with the trusses, then the original static loading requirement might not even matter.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

something I thought...why wouldn't the Fire Code provide a maximum occupancy for egress safety that could have prevented this.

Love the commentary around 0:14

And this would have prevented the party HOW?

So who gets sued here? Architect? Engineer? Contractor? City? Everybody?....

 

[SnTMan]

I'm guessing everybody but the college students. No money there

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Same thing happened to an 70 year old house beside mine at university 40 years ago (pogoing back then). They felt the floor getting soft and kept pushing it. My father told me about parking garages in England collapsing in the 30's from roof top dancing (swing era). That led to code changes. Those structures would have been stronger than those joists in the video. Too many small joints to stand up to the dynamic, and possibly resonant, loading.

It would have been funnier, if they were engineering students. Just glad no one was injured.

The tenants.

I'm with Spartan. I'd serve the tenants ASAP. I'm betting there was some rental/lease clause stating "no parties", these are students after all. If not, the landlord just got an expensive lesson.

At the bare minimum, someone's not gonna get their security deposit back.
