This guide presents recommendations for materials, analysis, design, and construction of concrete-pedestal elevated water-storage tanks. These structures are commonly referred to as composite-style elevated water tanks that consist of a steel water storage tank supported by a cylindrical reinforced concrete-pedestal. This dociment includes determination of design loads, and recommendation for design and construction of cast-in-place concrete portions of the structure. Concrete-pedestal elevated water-storage tanks are structures that present special problems not encoutered in typical building designs. This guide refers extensively to ACI 318 and describes how to apply ACI 318 to these structures. Determination of snow, wind and seismic loads based on ASCE 7 is included. These loads will conform with the requirements of national building codes that use ASCE 7 as the basis for environmental loads. Special requirements, based on successful experience, for the unique aspects of loads, analysis, design and construction of concrete-pedestal tanks, are presented
