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.
