That's because only one spot failed, and it was just the flooring between the joists. That was due to an insane amount of force applied to a small spot. It only affected that spot. The rest should be unaffected, especially with the small amount of pressure from their weight. Kind of like windshield glass. Tiny rock at high speed might make a chip, a hole, or a crack, but generally the rest of the windshield will function as normal and will be able to stop bugs and wind, even other small rocks. The whole thing doesn't go.

I kinda feel like the couple who thought "lets just have the chimney collapse on our wooden floor" isn't having intelligent thoughts about the layout of their floor joists.

Your comment made me think of Dr. Seuss, so I wrote a rhyme…
The pair got up early, They rose with the sun. “Let’s put on our sandals, There’s work to be done!”
“This room needs an update, I know just the trick!” And he pulled out a crowbar And popped off the brick.
The brick came off easy, Not much of a chore. But he moaned a small, “Oops” As it fell through the floor.
“What’s down there?” he wondered As they peered through the hole. “The fireplace brick, now, You stupid a-hole.”
“Plus grandma doing laundry,” She said with a gripe. “And Joey, the plumber, Who was installing new pipe.”
They quick packed their bags, And away they did go. From grandma and Joey, Both dead down below.

I counted 7 bricks across by 15 bricks high at 4.5 lbs a brick equals 472.5 lbs just in bricks. The mortar looks like a 1/3 the thickness of a brick so if we guesstimate another 156 lbs in mortar we have a total of 628.5 lbs hitting the floor with a total surface area of a bit over 200 square inches of impact area.
Edit: Common brick is 7.625 inches long by 3.625 inches wide. Thats 27.64 square inches per brick times 7 equals 193.48 square inches. If the mortar is a inch thick times 5 applications times 3.625 equals another 18.125 inches for a grand total of 211.605 of area that slammed into the floor.
If someone with higher math skills can figure out the speed when it impacts the floor we could see the lbs per square inch of pressure when it hit.
As just a average person even I knew that letting that piece hit the floor was going to be catastrophic...

So the wall is 56"x60", or 4'-8"x5'-0" = 23.3 sf. 4" clay brick and mortar weighs about 40 lb/sf. So 933 lbs total.

My estimate: ~24.8 ft/s
Using the very top of the brick as the reference point in motion:
initial velocity [V] = 0angle of launch [a] = 0°initial height [h] = 9ft (9’ ceiling?)time of flight [t] = blank (want this to be solved for)horizontal distance [d] = 4.5ft (best guess)maximum height [h_max] = 9ft
Time of flight [t] calculated as 0.7480s. Flight parameter at a given time:
time = 0.7479svelocity = 24.8037 ft/s right before impactLots of assumptions made and very apparent things ignored like the initial nudge in the horizontal vector he gave with the crowbar and the fact that the pivot point at the bottom of the cleaved brick means it wasn’t in free fall for the initial movement. Intuition tells me the centripetal force it creates shouldn’t be ignored, but I’m too lazy to google search for a more advanced online calculator to address a body in motion that transitions from a fixed point centripetal motion into free fall with rotational and translational motion.
Edit: decided to spend more thought on it.
- Angle change [Δa] = 90°
- Time [t] = 1.26 (best guess from time it starts to tip to the time it is parallel to the ground, aka 90°)
- Angular velocity (calculated) = 1.2467 rad/s
- Radius = 4.5ft
- Velocity (calculated) = 1.71 m/s
- Gravity acceleration = 9.80665 m/s2
- Initial velocity = 1.71 m/s
- Height = 4.5 ft (9' ceiling assumed)
- Time of fall (calculated) = 0.3825 sec
- Velocity = 5.461 m/s (17.918 ft/s to compare to my last estimate)

I mean... I think floors are supposed to have enormous redundancies for safety reasons, though, no?
The complete and total lack of resistance would seem to indicate that the floors weren't up to code.

u/Minimum_World_8863 2d ago
Floor loading is typically only like 50 psf from what I remember. It relies on the framing to disperse the load.
With these chuckle fuckes they managed to land it perfectly in a joist bay. And that floor looks like tissue paper and was probably relying on whatever floor they removed for some integrity.
The floors where likely we'll within code. Not a lot of floors are taking that much concentrated load between joists - with some velocity.
It's the equivalent of hitting it full bore with a sledgehammer.

u/pmormr 2d ago edited 2d ago
That floor system actually looks pretty decent... the joists look like 2x6's in good condition, spaced 12-16" apart. Should be plenty for a residential spot. The brick wall just laser targeted the weakest spot between two joists and the floor sheeting couldn't handle it. Honestly the best result these guys could expect because if it landed flat I don't think the floor would totally collapse but I'd be checking for structural damage afterwards lol. The floors in houses aren't built so you can drop a piano from head height on them... it's just not necessary.

u/65Kodiaj 2d ago
The problem is the bricks hit at the end of the plywood on top of missing the floor joists completely. Not that hitting in the middle if the plywood sheet would have made that much of a difference I believe.
I would pray that a floor joist would have stopped that but that much weight focused on a small area would still cause damage. How much depends on how strong the floor joist is.

u/cbarrister 2d ago
They are honestly lucky. It's going to be easier to patch the subfloor than it would be to replace a shattered joist.

u/Fspz 2d ago edited 2d ago
I wonder what would have happened if the joists were running the other way.
EDIT:
Others calculated 472.5 lbs of load and 5.46 m/s falling speed, if the joists were running the other direction it would be about 155 lbs per joist, which with that falling speed would be the equivalent of about 862 lbs or 391 kg per joist as a static load, which would put it to its limits but if the load is evenly distributed it should theoretically hold with little to no margin.If the wall was to fall just a little further with the actual joist direction and landed on a single joist, it would have for sure broken it, which could have caused more damage where it connects to the rest of the structural framing or walls.

The pressure on the floor depends on how pliable the floor is and how close you are to a cross-beam. That would be pretty difficult to calculate accurately.

Ok, ok, let's go for theoretical lbs per square inch on a solid floor impact. That would give us a maximum number to consider.

Looking for the pressure on the floor is the wrong way to assess how much more load is being put on the floor than it can take anyway.

u/loopy_soupy 2d ago
Pressure = force/area and force = mass x acceleration so pressure = (mass x acceleration)/area.
Ignoring air friction, acceleration = 9.8m/s2, plugging in 628.5 lbs and 211 square inches gets us to a psi of just under 3, or a pound per square foot of about 400.
Which doesn't sound like a lot, but below someone mentioned the rating for flooring - without joists, which is where this went through - is like 50 pounds per square foot, so this was well above the limit. Wonder how much different it would be if the joists were rotated 90 degrees instead of parallel to the fall path.

I know that it is a perfectly natural reaction to go checkout the hole, but that seems really dangerous given that the floor was just destroyed there. It was lucky that it seemed to slip between two of the beams supporting the floor but if it had severed those, walking over to the hole might have ended poorly.
