calculating the maximum floor load
could you tell me specificly how to calculate the maximum floor load for the following type of floor:
oak wooden floor of 1 inch thickness sitting on latts of approximately 3-5 inch square in thickness, and in turn sitting on 2-3 foot of stone (or up to one metre)?
hi:
you'll need to describe your floor a little better.
what are latts?
what does 3-5 inches square in thickness mean? all of this sits on stone which is 2 or 3 feet thick? are we to assume the stone is based on terra ferma or is it sitting on something else?
i think he is talking about what load he could put, drive, store on this floor.
by latts, i mean joists that are circa 3-5 square inches in size. it is on the first floor of a building. this floor is approximately up to 2 metres thick and made from stone and bricks. the rooms are small in diameter, and the walls on the first floor sit directly above those on the ground floor. they are approximately up to one metre in thickness.
what is holding up the actual floor? right now you have about 6.5 feet of stone, rock, brick with a weight of 120 pcf and an additional 7-9 psf for the oak and 'latts'. the total wieght of 1 square foot of that floor is around 790 pounds psf now. that is a large load in itself.
lorraine6,
i think we are all having difficulty imaging the floor framing system you describe.
is this floor system directly supported on the ground, or is is suspended?
this is possibly one of the main reasons drawings are the best form of providing construction information!
the floor would be suspended. i don't have the equipment to send photos, drawings, or images - sorry.
