Book Description
He inelastic behavior of irregular shaped reinforced concrete columns has been a constant concern for a structural engineer, to design a safe and economic structure in modern buildings and bridge piers. The shape of the elements in a reinforced concrete structure may be used to optimize its structural strength, to make better use of the available space, to improve the aesthetic appearance of the structure, or to facilitate construction. Due to the locations of the columns, the shapes of the buildings and the nature of the applied loads, many columns are subject to combined biaxial bending and axial load. Seven 1/4 scale direct models of the short, tied columns with channel-shaped cross sections were constructed for the present investigation. All the specimens were tested and studied for their complete strength and deformation behavior under combined biaxial bending moments and axial compression, and were used to examine some of the variables involved such as relative eccentricities and loading variations. The end conditions are assumed to be pinned-ended. The experimental load-strain and biaxial moment-curvature curves have been compared with the analytical results of the strength and deformation for biaxially loaded channel-shaped column members, and a satisfactory agreement was obtained from zero up to the ultimate load condition. The above inelastic behavior of channel-shaped reinforced concrete columns has formed the basis of the redistribution of the moments and forces in a statically indeterminate structure, and these characteristics can also be found useful for the limit analysis and design of reinforced concrete structures.

Book Description
Combined biaxial and axial compression for L-shaped reinforced concrete short columns is a common design Problem. Current code, provisions and the available design aids do not offer an insight into the determination of strength and ductility of biaxially loaded reinforced concrete column. An experimental and analytical investigation of the moment-deformation behavior of biaxially loaded L-shaped short columns were undertaken. Four 1/2 scaled specimens were tested till failure. Moment-curvature and load-deflection curves were developed from the experimental and the analytical results. The analytical results were obtained using a computer program developed by Hsu (1). From the investigation it is deduced that the computer program developed by Hsu (1) can be used to find the ultimate strength, the moment-deformation characteristics, the stress and the strain distributions across the section of L-shaped, biaxially loaded column with large and small eccentricities.

Book Description
The investigation deals with the effect of eccentric loading on the moment-curvature relationship of reinforced concrete tee columns. The test program consisted of two series of tee-shaped reinforced concrete columns, loaded biaxially at constant angle from the principle axes. Their end conditions were assumed to be pinned-ended. Loads, at constant rate, were gradually applied until failure. At each loading stage, measurements were made for the strains and deflections at the mid span section. The experimental and theoretical results of the load- deformation and moment-curvature were compared and found that the analytical approach proposed by Hsu is applicable to irregular sections such as tee columns, under small and large eccentricities, but tended to underestimate slightly the axial load and the moment-curvatures at failure.
