Abstract: Abstract of thesis entitled INELASTIC DESIGN OF REINFORCED CONCRETE BEAMS AND LIMITED DUCTILE HIGH-STRENGTH CONCRETE COLUMNS submitted by Ho Ching Ming Johnny for the degree of Doctor of Philosophy at The University of Hong Kong in January 2003 This thesis studies the inelastic analysis and design of normal- and high-strength reinforced concrete beams and high-strength reinforced concrete columns. Particular attention is given to the proposed design method of limited ductile high-strength reinforced concrete columns. Analytical studies on normal- and high-strength reinforced concrete beams and experimental research on high-strength reinforced concrete columns are conducted and discussed. To investigate the post-peak behaviour and flexural ductility performance of reinforced concrete beams and columns, the author proposes a new method of rigorous nonlinear moment-curvature analysis that incorporates the strain history effect of tension steel. The moment-curvature curves derived using the new method resemble more closely the actual post-peak behaviour of reinforced concrete members compared to their conventionally-derived counterparts. The results enable the author to derive: (1) a theoretical equation that correlates the curvature ductility factor of reinforced concrete beams to various structural parameters; (2) two sets of design ultimate concrete strains suitable for use with either the proposed equivalent rectangular concrete stress block or the equivalent rectangular stress block of BS 8110; and (3) a series of design charts that facilitates the concurrent design of flexural strength and ductility of reinforced concrete beams. A new parametric study using the proposed analysis method is also conducted to refine the author's previously-proposed equation on transverse steel content of limited ductile high-strength reinforced concrete columns. A series of high-strength reinforced concrete columns containing transverse reinforcement calculated in accordance with this refined equation are tested under compressive axial load and reversed cyclic inelastic displacements to assess its adequacy. These columns prove capable of achieving a curvature ductility factor close to 10, which is the commonly-accepted measure for limited ductile structures. They are subsequently compared with another series of columns containing transverse steel calculated in accordance with the shear requirement of BS 8110. The performance of the latter series is shown to be much worse than the former in terms of flexural strength and ductility. The influence of transverse steel configuration is investigated on some test specimens selected from these two series of columns. In addition, three column specimens are tested to investigate the effect of tension steel lap splice. The test results indicate that the lap splice should be located further away from the potential plastic hinge region. The author also proposes a rational evaluation of plastic hinge length, which could hitherto only be assessed empirically during experimental tests, using various methods that can be grouped into direct and indirect methods. The results are compared with the experimental data obtained from the majority of the column test specimens and with the experimental data obtained by other researchers, and they match closely. To facilitate the design of limited ductile hig

Book Synopsis Reinforced Concrete Beams, Columns and Frames by : Jostein Hellesland
Download or read book Reinforced Concrete Beams, Columns and Frames written by Jostein Hellesland and published by John Wiley & Sons. This book was released on 2013-02-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the theoretical and practical design of reinforced concrete beams, columns and frame structures. It is based on an analytical approach of designing normal reinforced concrete structural elements that are compatible with most international design rules, including for instance the European design rules – Eurocode 2 – for reinforced concrete structures. The book tries to distinguish between what belongs to the structural design philosophy of such structural elements (related to strength of materials arguments) and what belongs to the design rule aspects associated with specific characteristic data (for the material or loading parameters). A previous book, entitled Reinforced Concrete Beams, Columns and Frames – Mechanics and Design, deals with the fundamental aspects of the mechanics and design of reinforced concrete in general, both related to the Serviceability Limit State (SLS) and the Ultimate Limit State (ULS), whereas the current book deals with more advanced ULS aspects, along with instability and second-order analysis aspects. Some recent research results including the use of non-local mechanics are also presented. This book is aimed at Masters-level students, engineers, researchers and teachers in the field of reinforced concrete design. Most of the books in this area are very practical or code-oriented, whereas this book is more theoretically based, using rigorous mathematics and mechanics tools. Contents 1. Advanced Design at Ultimate Limit State (ULS). 2. Slender Compression Members – Mechanics and Design. 3. Approximate Analysis Methods. Appendix 1. Cardano’s Method. Appendix 2. Steel Reinforcement Table. About the Authors Jostein Hellesland has been Professor of Structural Mechanics at the University of Oslo, Norway since January 1988. His contribution to the field of stability has been recognized and magnified by many high-quality papers in famous international journals such as Engineering Structures, Thin-Walled Structures, Journal of Constructional Steel Research and Journal of Structural Engineering. Noël Challamel is Professor in Civil Engineering at UBS, University of South Brittany in France and chairman of the EMI-ASCE Stability committee.

Abstract: The stress-strain relationship of concrete in flexure is one of the essential parameters in assessing the flexural strength and ductility of reinforced concrete (RC) structures. An overview of previous research studies revealed that the presence of strain gradient would affect the maximum concrete stress and respective strain developed in flexure. Previously, researchers have conducted experimental studies to investigate and quantify the strain gradient effect on maximum concrete stress and respective strain by developing two strain-gradient-dependent factors k3 and ko for modifying the flexural concrete stress-strain curve. In this study, the author established a new analytical concrete constitutive model to describe the stress-strain behavior of both normal-and high-strength concrete in flexure with the effect of strain gradient considered. Based on this, comprehensive parametric studies have been conducted to investigate the combined effects of strain gradient and concrete strength on flexural strength and ductility design of RC beams and columns with concrete strength up to 100 MP a by employing the strain-gradient-dependent concrete stress-strain curve using non-linear moment-curvature analysis. From the results of the parametric studies, it is evident that both the flexural strength and ductility of RC beams and columns are improved under strain gradient effect. A design value of ultimate concrete strain of 0.0032and anew equivalent rectangular concrete stress block incorporating the combined effects of strain gradient and concrete strength have been proposed and validated by comparing the proposed theoretical strength with the strength of 198 RC beams and 275 RC columns measured experimentally by other researchers. It is apparent from the comparison that the proposed equations can predict more accurately the flexural strength of RC beams and columns than the current RC design codes. Lastly, for practical engineering design purpose, design formulas and charts have been produced for flexural strength and ductility design of RC beams and columns incorporating the combined effects of strain gradient and concrete strength.

Book Synopsis Strength of High Strength Concrete Columns Under Eccentric Compression by : R. H. Basappa Setty
Download or read book Strength of High Strength Concrete Columns Under Eccentric Compression written by R. H. Basappa Setty and published by . 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.
