Full Description

This standard covers current recommended practice for the design, construction, inspection, and maintenance of wire- and strand-wound, circular, prestressed concrete water containing structures with the following four types of core walls: cast-in-place concrete with vertical prestressed reinforcement; shotcrete with a steel diaphragm; precast concrete with a steel diaphragm; cast-in-place concrete with a steel diaphragm. This standard does not cover bonded or unbonded horizontal tendons for prestressed reinforcement of the tank wall, floor, or roof. This standard applies to containment structures for use with potable water or raw water of normal temperatures and pH commonly found in drinking water supplies. It is not intended for use in the design of containment structures for highly aggressive waters or high-temperature waters without special consideration being given to their effects on the structure; nor is it intended that the standard be used for the design of structures for wastewater, bulk dry storage, chemical storage, or storage of slurries. This second edition of the standard has been edited throughout and includes revisions to standard definitions and terms. Provisions for earthquake-induced forces, formerly attached to the standard as appendix A, have been incorporated into the standard as Sec. 4 and updated in accordance with experience and current practice. Finally, 15 technical revisions to the standard reflect current thinking and construction practices.

This addendum to ANSI/AWWA D110-95 Standard for Wire- and Strand-Wound Circular-Prestressed Concrete Water Tanks revises or replaces Sec. 4.3.1(4); Sec. 4.3.2; and Sec. 4.5.3, Equation 4.24.
