How to Design Cylindrical Tanks? Civil Engineering

Cylindrical tanks may have flat bottom or spherical bottom or conical bottom.A flat bottomed cylindrical tank having a height greater than the diameter is called a stand pipe.Such a tank rests on the foundation directly.The tank may also be provided with a conical roof.Stresses in Stand Pipes Bending Stress Overhead Cylindrical Tanks: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.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.
