Greg from North Dakota wrote us and asked us to please solve this very
problem because he was trying to design a hot tub deck to withstand 8,000
lbs of force.
Greg's hot tub was 8'x8'. A very common size but he wanted to design his deck so
that the top of the hot tub sat flush with the deck surface.
But the surrounding deck was fairly high off the ground so the hot tub
had to be supported by an elevated substructure.
The software made a breeze of this little hot tub conundrum and gave a number
of options for beam sizes, post sizes, joist sizes and footings.
Read all about it in the pdf
version prepared by Tim Garrison.
Also read each of the following reports on beam
size, joist size, post size, and footings to
see how Greg's question about hot tub deck design was answered.
