Supporting methods for inclined-bottom storage tanks
Thread Content
For a 25m3 oil storage tank (with a diameter of 3m) operating at atmospheric pressure, it is intended to have an inclined bottom; per the standards, this requires an inclined foundation. If no foundation is used, is it feasible to use diagonal rebar for support? Is the weld at the junction of the slope and the tank wall, which lacks support, needs to be reinforced? Seeking advice
Generally, T-shaped or H-shaped steel is used at the bottom of the tank, with a spacing of five to six hundred units; the design is based on calculations of the combined bending moment capacity. For inclined surfaces, the loads need to be broken down, but it’s a bit complicated and I haven’t carried out those calculations yet.
I have already implemented this for you before; adding diagonal braces as support works； The weld at the junction of the slope and the tank wall, which lacks support, also needs to be reinforced
I’d like to know why it’s made at such an angle
