SP50-12

Date: 

January 1, 1975

Author(s):

Carl Berwanger and S. Imtiaz Rasul

Publication:

Special Publication

Volume:

Abstract:

Experimental and analytical investigations of fifty-five partially prestressed concrete beam-columns undergoing transverse flexure combined with axial thrust have been conducted. The tests were of short term duration. The variables were the number and the arragement of the prestressing tendons and the total prestressing force.

Abstract:

The investigation deals with the effect of axial load on the moment-curvature relationship of reinforced concrete memebers. Uniaxial loading when combined with transverse flexure generally reduces the ultimate moment and curvature of these members.

Abstract:

A comprehensive but simple design procedure is presented for the design of concrete columns subject to biaxial bending. The procedure is oriented towards hand computation but is suitable for incorporation into computer programs. The methods in the existing literature are summarized and evaluated. A new design procedure and an example problem showing its use are given.

Abstract:

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.

Abstract:

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.

Abstract:

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.
