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.

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 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.

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.

This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 1993 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rational analysis of reinforced concrete (R/C) structures requires satisfactory modeling of the behavior of concrete under general loading patterns. The behavioral characteristics of concrete dominantly depends upon its load history. For the study of concrete behavior, parametric study and experimental investigation into the behavior of concrete under load history of random cycles are performed. Through parametric study, the applicability of the previous concrete models is examined and a physically motivated modeling for the cyclic stress-strain relationships is proposed. The present modeling of concrete under general cyclic loading is initiated to provide substantial applicability, flexibility of mathematical expressions and furthermore to describe the behavior of random cycles. For the experimental study of concrete subjected to cyclic axial compressions, tests of 3 in. by 6 in. concrete cylinders are conducted under four different loading regimes to determine the major experimental parameters for the proposed analytical expressions. The model developed is based on the results of parametric study and experimental data obtained for the present study. The validity of the proposed general cyclic model is confirmed through a comparison of the experimental results and simulated behavior of the model. Furthermore, the analytical model proposed has been idealized and incorporated into the procedures in analyzing RIC columns. The behavior of R/C columns having various properties and subjected to a variety of loading conditions have been the topics of considerable investigation. Of particular significance in the area of unexplored problems is the behavior of R/C columns under cyclic compressive load. It should be noted that cyclic loads with bidirectional eccentricities considered are in the longitudinal direction, and not in the transverse direction, with respect to the column axis. For the experimental investigation, tests of four foot long columns are conducted under stroke control to achieve both ascending and descending branches of the load-deformation curves. Analysis of RC columns subjected to cyclic axial compressions with bidirectional eccentricities should be approached from the standpoint of a three dimensional problem. A numerical procedure based on extended finite segment method is proposed here to predict the ultimate load, deflections and moment-curvature of experimental results. It is found that the proposed numerical analysis can reasonably simulate the loading and unloading behavior of R/C columns under combined biaxial bending moments and axial compressions.
