Hello. Does the hot tub load the deck at the four walls only?
I will assume it loads the deck at the walls only.
2x10 are too small to span 12' supporting the tub. You should use 2x12 under the are with the tub and triple the two that are directly below the hot tub walls and parallel.
Then you can double the 2x10s directly under the walls of the hot tub
A psf load rating is not meaningful because the hot tub doesn't load the deck uniformly. It loads it with four line loads. You must double those joists
Hello. Do you have any other questions on this topic? If you could rate my answer, I would appreciate it.
