An incremental rate-of-creep analysis of reinforced concrete columns subjected to sustained loads is developed and used to generate data for a statistical evaluation of the stiffness, EI, of slender concrete columns subjected to short time and sustained loads. The resulting equations are more accurate than ACI Eqn. 10.7 and are as easy to use. The possibility of column failure under very high sustained loads is discussed.

The purpose of this work is to develop a simplified procedure for estimating the effects of tension cracking, nonlinearity of concrete in compression, yielding of the steel, and the effects of secondary bending on the displacements and moments in eccentrically loaded columns bent in single curvature.

A design method is described for symmetrically reinforced slender square concrete columns under biaxially eccentric loads. Dimensionless charts are presented giving the relationships between load, eccentricity, and curvature. Comparison of the method with existing results shows good agreement.

Present equations of design of tied reinforced concrete columns do not include for the influence of ties on the value of the ultimate load. . .Theoretical analysis of a segment of a tied concrete column is presented showing the distribution of strains in the concrete, longitudinal steel and ties.
