Another consideration for setting tank foundations is the possibility of buoyancy of the tank due to submergence in water. Plane flat bottom,For Tank Anchorage,Overstrength Factor,and Overturning My question relates to ASCE 7 Chapter 15,particularly 15.7.5.I am designing the anchorage for a saddle supported liquid storage tank.Section 15.7.5 makes it clear that the overstrength factor is NOT to be used for tank anchorage calculations,because they are trying to force a ductile yield in the anchor,requiring the concrete to develop the full steel strength of the anchors in tension.

TANK BOTTOM SUPPORT PAD BELDING TANK flat bottom and slope bottom tanks require continuous bottom support.The most common support pad is a concrete slab.However,any other support structure with sufficient strength to support the combined weight of the tank and its contents,with a reasonable factor of safety,is acceptable.Foundations of aboveground steel tanksc) flat bottom without slope It can be applied in the small tanks where the removing of the water dropped inside into the tank is not required.d) flat bottom with single slope.Can be applied where the diameter D 30 m.This type of bottom requires sloped foundation and the construction of the shell must assure its vertical position.2.External pressure limitations for 0--15 psi storage tanks Buckling or uplift of the dished bottom and cylindrical sidewall portions of the carbon steel liners are investigated for each of the twelve SST tank farms taking into account predictedmore The additional vacuum in excess of the self-weight and residual waste to cause uplift of flat bottom tanks (A and AX) or buckling of the dished bottom
