ACI 371R-08

This guide presents recommendations for materials, analysis, design, and construction of concrete-pedestal elevated water storage tanks. Both the all-concrete tank and the composite tank, consisting of a steel water storage vessel supported on a cylindrical reinforced concrete pedestal, are included.Concrete-pedestal elevated water storage tanks are structures that present special problems not encountered in typical environmental engineering concrete structures. This guide refers extensively to ACI 350 for design and construction of those components of the pedestal tank in contact with the stored water, and to ACI 318 for design and construction of components not in contact with the stored water. Determination of snow, wind, and seismic loads based on ASCE/SEI 7 is included. These loads will conform to the requirements of national building codes that use ASCE/SEI 7 as the basis for environmental loads or conform to the requirements of local building codes. Special requirements, based on successful experience, for the unique aspects of loads, analysis, design, and construction of concretepedestal tanks are presented.
