With 8,000 lbs of hot water and people your hot tub deck design had
better be engineered to stand up to the test or it could be disasterous.
I have received a lot of emails from visitors asking us how to actually
design and calculate the loads and forces that a typical hot tub exerts
on a deck.
And I'll admit, if you are building a deck for the first time, this
is one occasion where you don't want to make a mistake. Hot tubs with
water and people are heavy.
But how do you design a deck to easily support a hot tub?
What size of posts do you use?What is the right joist span?How big
should the joist be?What about the beams?
Well, without doing some load calculations you will only be guessing...
and potentially flirting with disaster.
Thanks to Builder's Engineer they have developed a very useful software package that is useful
for average folks to do all kinds of load calculations, stair layouts,
joist, beam and post size calculations.
So on behalf of all our visitors to DecksGo.com we sincerely thank Tim Garrison, the guru behind all the Builder's Engineer for his very thorough explanation of hot tub deck design.
