Publication: Journal Proceedings
Appears on pages(s): 610-611

Abstract:This report gives material, construction, and design requirements for reinforced concrete chimneys. The report sets forth recommended loadings for the design of reinforced concrete chimneys and recommended methods for determining the stresses in the concrete and reinforcement resulting from these loadings. Charts containing curves to aid in the rapid solution of the specified formulas are included. Whi e the method of analysis applies primarily to chimneys, it can be used for other hollow or circular cross sections, with or without openings, where the shell thickness is small in proportion to the diameter. Formulas are recommended for determining the temperature gradient through the concrete resulting from the difference in temperature of the gases inside the chimney and the surrounding atmosphere, together with methods for determining the stresses in the concrete and reinforcement both vertically and circumferentially due to the temperature gradient through the concrete. Formulas for combining the stresses due to dead and wind (or earthquake) loads with the stresses due to temperature are included in the specification, together with recommended allowable stresses in the concrete and reinforcement for the various stress combinations. The specification refers to the ACI "Building Code Requirements for Reinforced Concrete" (ACI 318) for applicable requirements with supplemental provisions to take care of the special requirements for concrete chimneys. Appendices 1 and 2 review current (1968) practices or inings for concrete chimneys, for lightning protection, obstruction lighting, access ladders, and other chimney accessories.
