Will my floor take the weight...?

[si_sphinx]

I have just moved house and Im wanting to set up my tank (2.0m x 0.6m x 0.6m) and i need to know if the current timber flooring will take the weight of the tank and everything else.

So i have done a few calculations to try and figure out if it will be ok or not.

This is what i have worked out so far.

I'm not sure if they are correct but I'm sure someone here will know.

Tank-300kg (10mm glass)

Water-700kg

Stand-200kg

Sump-100kg

Rocks-100kg

Substrate-50kg

Total-1450kg (1500kg roughly)

these weights are all estimates only

Stand-60cm wide by 200cm long = 12000cm^2 base area.

1500/12000 = 0.125 kgf/cm^2

kilograms-force/cm^2

(kgf/cm^2)*98.1 = kPa

0.125*98.1 = 12 kPa of force bearing down on my flooring

Floor framing: (this is all i know about it without taking more measurements).

T & G floor boards

Joists-125x50 @ 450crs, spanning 1500mm

Bearers-125x100 @ 1500crs, Spanning 1500mm (span is guesstimated)

All the timber framing is rimu and in good condition, no cracks,splits,bowing,twisting,rotting, nothing. not even borer.

I was never good a math so this is me trying my best and I am pretty sure I would have gone wrong somewhere.

All these calculations are to see how much i will need to brace the floor framing (I have full intentions of doing this if i need to or not.)

What I'm wanting to know is...

-Have i done the calcs right to find the correct kPa loading of the tank

-Just how much force/weight could my flooring take and is there a calculation to find out?

i had my floor done for my 500l tank and our floors were very good.

One of the most important considerations is to make sure that the joists are at right angles to the wall that you want to put the tank against and not parallel to it.

[livingart]

don't forget to add your weight for when you are working on the tank or more than one person standing and viewing it closely

been there and done that

brace it anyway for piece of mind

your over the top with the weight of the glass

glass weighs 2.5kgs per square meter x the thickness

.600 x 2.000 = 1.2(area) x 2.5kgs = 3kgs x 10mm thick = 30 kgs x 3 = 90kgs

.600 x .600 = .36 (area) x 2.5kgs = .9kgs x 10mm thick = 9kgs x 2 = 18kgs

108kgs plus lid and bracing

You have a hundred kgs of rocks?And your stand's 200kgs? you sure??

[suphew]

My ~800l marine doesn't have any extra floor support and has been fine for round 7 years now. It is against a load bearing wall and runs cross the joists.

your floor might sag

[si_sphinx]

the tank feels heaps heavier than 108kgs could be just the awkwardness of it :lol:

the tank will be laying across the joists not along them.

ok so the stand probably not that heavy. made from 100x50 rough sawn pine. but still heavy. (id rather measure too much than not enough)

I'm going to get under the floor and brace it anyway just to be safe.

Simply weigh it then.

But those are the calcs we use in the trade so Im picking that they are corect
