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.

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.

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.

This book is the companion volume to Design of High Strength Steel Reinforced Concrete Columns – A Eurocode 4 Approach. This book provides a large number of worked examples for the design of high strength steel reinforced concrete (SRC) columns. It is based on the Eurocode 4 approach, but goes beyond this to give much needed guidance on the narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete. Special considerations are given to resistance calculations that maximize the full strength of the materials, with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. These examples build on the design principles set out in the companion volume, allowing the readers to practice and understand the EC4 methodology easily. Structural engineers and designers who are familiar with basic EC4 design should find these design examples particularly helpful, whilst engineering undergraduate and graduate students who are studying composite steel concrete design and construction should easily gain further understanding from working through the worked examples which are set out in a step-by-step clearly fashion.

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.
