Title: Design Equations for Hollow Circular Sections of Reinforced Concrete Without
Thin Wall Approximation
Author(s): Wen-Foo Yau
Publication: Journal Proceedings
Appears on pages(s): 506-510
Keywords: chimneys; eccentric loads; loads (forces); reinforced concrete; stresses; structural analysis; structural design.
Abstract:Three equations are derived for the calculation of loading eccentricity and maximum stress in reinforced concrete chimney-like structures without use of a thin wall approximation. These equations are proposed as substitutions for the corresponding equations of "Specification for the Design and Construction of Reinforced Concrete Chimneys (ACI 307-69)" Results computed by the proposed equations are discussed and compared with those obtained from the existing equations. Under usual loading conditions, the proposed equations result in a more economical design.
