Book excerpt: 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.

This book was released on 1984 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Slender reinforced concrete columns have become widely used as structural members in recent years. Current Codes of Practice for Structural Concrete lack sufficient guidance to designers for their safe and efficient design. This investigation studies the behaviour of very slender, pin-ended, reinforced concrete columns, under short-term and sustained loads, by experiment and theoretical analysis. A new approach is used in the method of applying load to the column. A concentric axial load and independant primary end moments are considered. This allows the determination of secondary moments due to axial force and secondary deflections to be easily determined compared with the conventional eccentric load methods adopted in the past. A non-linear, second-order computer analysis has been developed which is capable of accurately predicting the deflections of hinged columns throughout the loading range from zero load to buckling failure, for any combination of eccentric loads and primary moments for short or sustained periods. It has the potential to accept end restraint in order to model framed columns. An extensive experimental programme of tests has been performed on 48 column specimens with slenderness ratios between 29 and 59 under short term loads and 5 specimens under sustained loads for up to two years. A total of 68 short column specimens with an identical section to the slender columns and material specimens were also tested. The specimens had a mean wet-cured cube strength of 42 N/sq.mm. The results of these tests and, 120 similar results of other authors, confirmed the validity of the proposed theoretical analysis and the assumptions used. The computer program which is presented could be made available to design offices for use on a basic micro-computer. The design methods recommended by three Codes of Practice, CP110:1972, ACI318:1977 and CP114:1957, have been compared with the experimental and theoretical results of this work. CP110 and ACI318 are shown to give conservative designs, with an overall load factor of 3.0 and 2.4 respectively, for design loads compared with the 25 year load.

This book was released on 1984 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1984 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Next to rectangular, circular and L shapes, Channel section may be the most frequently encountered reinforced concrete columns since they can be used as box wall for elevators. Nevertheless, information about the load deformation behavior is not generally available to structural engineers. Most of the investigations have been emphasized on the ultimate strength of column sections under combined biaxial bending and axial compression and the resulting interaction surface. No attention is paid to load deformation behavior. Current code provisions do not provide adequate guidelines for assessing the strength and ductility of biaxially-loaded reinforced concrete columns. Therefore, this investigation is aimed at an experimental and analytical study of the behavior of biaxially-loaded channel- shaped short columns as the applied load is increased monotonically from zero to failure. For the test purpose four reinforced concrete Channel shaped columns of nearly half the size of the true specimens were casted and tested till failure. Moment-Curvature and Load Deflection curves obtained from testing channel section were compared with the results from a computer program developed by Hsu1 and were found to be in excellent agreement. In addition a computer program was developed to calculate the ultimate flexural capacity of cracked arbitrary concrete sections under axial load and biaxial bending based on the Brondum-Nielsen s paper.

Download or read book Behavior of Square and L-shaped Slender Reinforced Concrete Columns Under Combined Biaxial Bending and Axial Compression written by Wen Hu Tsao and published by . This book was released on 1992 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical analysis was developed to evaluate the complete load-deflection and moment-curvature relationships for square and L-shaped slender reinforced concrete columns subjected to biaxial bending and axial load. This computer model can be used for any cross section geometry and material properties of normal concrete. The analysis was based on a deformation control and both the ascending and descending branches of curves can be studied. The finite difference method was introduced to calculate the deflections which satisfy the compatibility equations. Six square slender columns and eight L-shaped slender columns were tested to compare their experimental load-deformation results with the analytical results derived from the theoretical studies. A satisfactory agreement was achieved for the present study. The results of present study can be used for future design reference.
