A questions for any structural engineers

but the 2 x 10 have no where to go....they are completely supported by the retaining wall below them...they would basically have to be crushed for them to go anywhere or the retaining wall would have to be pushed down.
as well the the retaining wall will be dead centre of where the tank is going to be above it. so the tank will be stradling the wall.
as for the stand ends, I woudl be running a 3 x 3 beam along the bottom of the stand along the floor. that way the weight will be dispersed along the entire length.

how wide are the stands? if they are 2' then you are only supporting 250lbs/ft
with the added support you will be fine

the stands will be 2 foot wide.
I will also be putting cross members from one truss to the other along the 2 8 foot spans(probably at 2 foot intervals) and along the sides.
that way it can't go anywhere.
unfortunately, I no longer have access to the crawl space.
but I think we did put braces anyways.
I will definitely be posting pics of it when it is up and running and probably as it gets to that point as well.
this will be one of 5 systems I am going to have in my house.

The beam at the bottom helps a bunch. I was under the impression this would be point loaded at the feet of the stand. If you can truss the bottom beam into the uprights, that will help keep the load spread out. I would also still suggest putting braces in between the joists immediately below the tanks, to prevent them from buckling sideways.. especially near the retaining wall.

would love to see some pics of the setup when its all together.. sounds like quite the operation.
