New level in hoarding reached: floor collapse

[NoTine42]

Yeah, I'm curious how that system works. Let's say you had a theoretical person that weighed 1000lbs and was standing on one foot tippy toes, does he fall through? How does it work between a spread load and something very focused? I imagine the spread load is being supported by the beams, but the focused could just be on the floorboards.

Load rating != failure rating

Load rating is about "comfortable" beam deflection.

Plywood and OSB subfloors are speced differently. There is generally less talk about their strengths.

I live in the area, the local TV news shows were running this story every five minutes yesterday. As I recall, they reported/speculated that there was unrepaired roof damage and the leaking may have weakened the floors.

Too bad, but at least her mental illness didn't hurt other people-unlike the school shooters.

Hoarders be too focused on their precious than anything around it.

Not violently... but hoarders do impact, severely, close family members and, to a lesser extend, neighbors.

lulz... That person in my family will deliberately break shit if he can't have it so no one else can benefit -- scorched earth. Examples? Old fridge that hadn't been used in decade: he cut the tube with coolant and let it leak out right after putting it on the curb. Someone ELSE'S old toilet he hauled home: took it in the backyard and broke it with a sledge hammer.

LOL some men just want to watch the world burn

Former structural engineer tech here. Yikes, in Canada it is 50lbs per square foot live load (40 where Greeman lives.), you had it at 125.

But! The problem with designing for 50lbs is that those weak floors tend to have too much sag, you walk by a china cabinet and it tilts away from the wall as the floor moves. Plus there is always an over factor built in too. Most floors will do 100lbs.

Yeah I was probably pushing it there. My floor is 2x10 joists, that wall is also on a triple 2x10 beam as it's a split level house so that's the end of one level. The floor is actually diagonal 1x6 planks. Then the sub floor for the tiles (3/4" ply if I recall). But yeah, after loading that there, I got kinda nervous then moved them to the basement. Older house too, so probably better built than the new stuff today.

You don't want the structure to deflect more than 1/360 of the span, thats what the 40 PSF is designed to meet, but the structure will take far more than the live and dead load it's designed to hold. Think about a 250 pound man jumping up and down, the impact load is huge, but the material handles it. I couldn't imagine what the actual failure load would be, but it's a lot.

Lots of google-fu engineers up in this thread.
