The standard gives material, construction, and design requirements for circular cast-in-place reinforced concrete chimneys. It sets forth minimum loadings for the design of reinforced concrete chimneys and contains methods for determining the concrete and reinforcement required as a result of these loadings. The method of analysis applies primarily to chimneys. This standard is written in explicit, mandatory language and as such is intended for reference in project specifications. Equations are provided for determining the temperature gradient through the concrete resulting from the difference in temperature for the gases inside the chimney and the surrounding atmosphere. Methods for combining the effects of dead and wind (or earthquake) loads with temperature both vertically and circumferentially are included in the standard. These methods permit the designer to establish minimum concrete and reinforcement requirements. The standard refers extensively to the "Building Code Requirements for Reinforced Concrete" (ACI 318); construction requirements are generally in accordance with ACI 318; and notation and terminology are in accordance with ACI 104.
