Default Re: Too much weight- floor collapse?

David had the correct response as usual. How many joists. What spacing. how wide each one, and how deep.
Not sure offhand the transverse strength of joist timber (i have it somewhere) but you could calculate the floor's strength.
I had an old set of volumes on building construction, and this subject was addressed there. If memory serves, the first regulations regarding flooring timbers came from the LCC (London county council) in about 1902, and slowly updated thereafter and adopted for all areas.
The UK has building regulations, almost certainly available online, which probably include calculation info.
Start off with the numbers and sizes of the timbers.
I have just found a copy of Spon's Practical Builder's Pocket book from 1937, and it has strengths of timbers in there. Probably much more. I will look later.
