Moving houses, need opinions on floor bracing

[FSJGUY]

You guys wannna see my tank and stand lol.. This is my 135 in my bedroom... note 4 legs.. Imagine 4 pointed legs on a subfloor with a 1500lbs tank/stand combo... And my joists are running length wise of the tank...

The only things i did to help with weight was weld some plates under the legs then add the wood under to help distribute the weight on the subfloor a little better... What i really need to do is drain the tank and cut some 2x4's and hammer them under the length of the stand so they better distribute the total weigh along the length of the floor.. Regardless i havent noticed any odd sagging.. I did have to shim the left side about 1/3 inch higher then the right side though. But that could be from the house shifting.. there are alot of places in the house i can put a marble on the floor and watch it roll.


Youre bracing looks good.


Remember bridges.. they move.. buildings move.. if nothing moved itd all break apart.. Floors are designed for movement.. if they didnt move they would come crashing down.. when you walk on the floor movement is being transfered to accross the room you just dont see it

Oh boy, I didn't think I'd have to break it down.

The high heel comparison is something we use all the time (in carpentry) to put into perspective how strong wood is structurally, and how distribution of load helps to carry the weight. I never said a woman is 20,000 pounds lol

If your floor can withstand 20,000 PSI from a high heel, once you break down the weight of the tank, rock and stand and do all your wizardry in math, you'll be looking at a far lower number per square inch where the stand contacts the floor.


Not sure what you're trying to accomplish.

Cheers.

What I was just commenting on was just saying how a point load (like from a high heel) is really about the punch through of the subfloor and says nothing about the distributed load capacity of a floor..

One must evaluate both as a separate calculation as one can't extrapolate one into the other.. When looking at if a stand/tank will be ok on a floor they must look at the distributed load calcs and then yes if that stand has feet then they should also look at the punch through rating of the floor..
A miscalculation in punch through could lead to a leg poking through the subfloor but its not going to mean that the floor itself will collapse.. And while one might determine that the legs won't poke through the subfloor but that doesn't say that the floor itself won't collapse..

So I commented that one cannot apply one to another.. I cannot determine anything about a floors distributed load by simply knowing its point load capacity and visa versa..
Thats it..

Wasn't trying to argue.. Just clarifying/passing along the difference..
Cheers again..

Thats why i just used steel welded to the legs then used pressure treated 2x10 under that this way it distributes the weight along 10 inches at the point of pressure

This is a good article on all the myths associated with heavy aquariums in the home. It appears to be written by a structural engineer.

Yes that link (not sure I've seen any others like it) should be the only response posted when a thread is started on this topic.. It seems to cover just about everything and is written to where most people regardless of their education should be able to understand it "enough"..
