Design loads for counter tops
Design loads for counter tops
(OP)
Sorry for this off-the wall- question, but need to know. I am a structural engineer in building design. However, I am asked from time to time to help architects design supports for counter tops. Not hardly main building structure, but asked anyway and I try to help.
I can't find a document or reference for what would be a good point load to use for counters. Don't find in code, and Google hasn't helped so far. I would expect that as much as 200 lb would be normal in case someone sits on it.
Anybody know what's typically done?
Thanks!

I have never designed a countertop, but maybe you should use residential loading, i.e. 40 psf plus an allowance for a roving concentrated load of about 400# spread over an area of 30" x 30".

I wound up using DL plus 3 - 200 lb point loads at equal spacing. The counter is about 16' long. I sized a tube to limit deflection to protect surface - has lots of reserve strength capacity.
