This standard describes current and recommended practice for the design, construction, and field observations of concrete tanks using tendons for prestressing. This standard applies to containment structures for use with potable water, raw water, or wastewater.
Description
The Second Edition of this standard incorporates the following major revisions: the Standard ANSI/AWWA D115 title is changed from "Circular Prestressed Concrete Water Tanks With Circumferential Tendons" to "Tendon-Prestressed Concrete Water Tanks"; the scope of the standard is expanded to include rectangular and other noncircular shapes as may be applicable (oblong, rectangular with rounded corners, etc.) and to allow the use of unbonded tendons as provided for in this standard; Section 1 references have been updated; Section 2 material standards are updated for cement grout, aggregates, admixtures, reinforcement, sheathing, bearing pads, and shrinkage compensating grout; Section 3 design standards are updated for wall footings, floors, walls, vertical reinforcement, construction joints, and concrete and shotcrete cover; Section 4 seismic design calculations are removed from the standard and replaced with references to appropriate ACI on Standards; and, Section 5 construction procedures are updated for tendon ducts, and grouting.
