Available in PDF, EPUB and Kindle. Book excerpt: Strength and deformation characteristics of 10 square confined high-strength concrete columns were investigated. Properties of columns were selected to allow assessment of the importance of confinement parameters for high-strength concrete columns. The specimens were tested under constant axial compression and incrementally increasing lateral deformation reversals, simulating seismic action. The data indicate that high-strength concrete columns can be confined to behave in a ductile manner. The volumetric ratio of confinement reinforcement required for high strength concrete columns is higher than that required for normal-strength concrete columns, although the spacing requirement does not appear to be a function of concrete strength. Columns confined with higher grade lateral reinforcement require lower volumetric ratios of confinement steel. The arrangement of lateral reinforcement plays an important role on improving deformability. Columns confined with well-distributed longitudinal reinforcement, laterally supported by transverse reinforcement show improved deformability. The volumetric ratio and spacing limitations for these columns need not be as stringent as those required for less favourable steel arrangements. Axial compression reduces column ductility. An analytical investigation was also conducted to assess the applicability of conventional analyses techniques used for normal-strength concrete columns to those made with high-strength concrete. The applicability of a confinement model, based on test data under concentric compression, was verified against experimental data. The results indicate that the confinement model can be employed to columns under combined bending and axial load. Furthermore, moment-curvature relationships obtained by plane section analysis, moment-rotation and force-displacement relationships obtained by integration of curvatures and consideration of column plastic hinging region, as usually done for columns with normal-strength concrete, produce fairly accurate representation of experimentally observed force-deformation relationships.

This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, high-strength concrete (HSC) has gained a more widespread acceptance in the construction industry. In spite of the advantages inherent to HSC, concerns still exist about its relative brittleness, particularly in regions of high seismic risk. An experimental and analytical investigation was conducted to study the behaviour of circular HSC columns subjected to simulated seismic loading. The experimental program included the testing of nine full-scale circular columns under combined axial compression and lateral load reversals. The emphasis was on the strength and deformation characteristics in relation to various confinement parameters. These parameters included the compressive strength of concrete, the yield strength, volumetric ratio and spacing of transverse reinforcement, the level of axial load, the type of circular reinforcement, and the presence of the concrete cover. The effects of test parameters were analysed by comparing the force-displacement relationships among pairs of companion specimens. The results show that ductile behaviour can be obtained from HSC columns subjected to lateral deformation reversals, provided they are suitably confined. (Abstract shortened by UMI.).

This book was released on 1995 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research work involved a study of behaviour and strength of eccentrically loaded High Strength Concrete columns. The research comprised experimental and analytical components. With regard to experimental work, twelve columns were manufactured and tested to failure. All columns were rectangular in cross-section with 300 mm x 100 mm as dimensions. The test specimens were loaded about the minor axis. The ratio of longitudinal reinforcement was either 1.47% (4 - 12 mm diameter bars) or 2.2% (6 - 12 mm diameter bars). The lateral reinforcement was in the form of rectangular closed ties made of 6 mm wires (W6). The spacing of ties was generally 50 mm, but, was decreased to 30 mm, at either ends to avoid premature failure.

This book was released on 1994 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to significant economic and structural advantages associated with the use of high strength concrete in compression members, the application of high strength concrete in columns and core walls is increasing. The advantages of using high strength concrete are well documented. Utilisation of high strength concrete leads to a reduction in column size. However, this results in an increase in slenderness of columns which would otherwise be stocky when built using low strength concrete. In addition, columns are rarely designed for pure axial load yet most research to date has focussed on high strength colurnns subject to concentric compression. Very limited data is available on columns subject to eccentric compression. The present research therefore focussed on slender columns subject to eccentric compression.

This book was released on 2016 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technique of using Carbon Fiber Reinforced Polymer (CFRP) materials to repair and strengthen various concrete members has become popular in the structural retrofitting field as an effective way to enhance the strength and ductility of concrete members due to its superior mechanical properties. In this study a method was introduced to study the behavior of concrete columns with and without CFRP jackets under constant axial load and variable lateral load. The lateral load was applied monotonically and cyclically. To predict the behavior of concrete columns under monotonic and cyclic compressive loadings, a computer code was developed to produce the moment-curvature diagram for concrete sections. The moment-curvature diagram was then input in SAP2000 to study the behavior of reinforced concrete columns. The result of this analysis was found to correlate with experimental data well. The behavior of high-strength concrete (HSC) columns having various properties and subjected to a variety of loading conditions has been the topic of considerable investigation. Of particular significance in this area is the behavior of HSC columns under cyclic compressive load with bidirectional eccentricity. For the experimental investigation, tests of six square slender HSC columns were conducted under stroke control to achieve both ascending and descending branches of the load-deformation curves. Analysis of HSC columns subjected to cyclic axial compression with bidirectional eccentricity was approached from the standpoint of a three-dimensional problem. A computer program based on the extended finite segment method and accounting for geometrical nonlinearity has been proposed here to predict the load-deflection curves of HSC columns under cyclical loading. The HSC stress-strain relationship obtained by parametric study and experimental investigation into the behavior of concrete under cyclical load history has been incorporated into the numerical procedure. The presented computer analysis results have been compared with the experimental data, and a satisfactory agreement was attained for both the ascending and descending branches of the load-deformation curves.

Book excerpt: The use of high-strength concrete for bridges and high-rise buildings become popular due to development in concrete technology and availability of various types of mineral and chemical admixtures. High-strength concrete could lead to smaller member sizes for compression members and therefore provide considerable savings associated with material costs and reduction of dead loads. However, Most of the current design codes, such as AASHTO-LRFD Bridge Specifications, are still based on tests conducted using normal-strength concrete. Many studies indicate that the behavior of columns with high-strength concrete is different from that of normal-strength concrete. The experimental phase of this investigation consists of thirty two rectangular and twenty four circular columns subjected to concentric and eccentric loading conditions to investigate the behavior of high-strength concrete columns. The main variables considered in this study were concrete strength ranging from 7.9 to 16.5 ksi, shape of cross section, and longitudinal and transverse reinforcement ratios. Using the test results of this study and other researches in literature, the dissertation provides design equation to predict the capacity of high-strength concrete columns with tie and spiral reinforcements subjected to concentric and eccentric loading conditions up to 18 ksi. The research also proposes a new stress-strain relationship of high-strength concrete confined with spiral reinforcements.
