Abstract:
Using a number of design standards as references, load combinations applicable to in-ground reinforced concrete tanks for nonhazardous liquids are reviewed. The review shows that only one of the cited standards prevents the designer from using lateral earth pressure to counteract hydrostatic pressure in the most basic load combination. The reasons for and against this requirement are discussed, along with other considerations such as tightness testing and reducing the potential for leakage.
