High-strength materials offer alternatives to frequently used materials for high-rise construction. A material of higher strength means a smaller member size is required to resist the design load. However, high-strength concrete is brittle, and high-strength thin steel plates are prone to local buckling. A solution to overcome such problems is to adopt a steel-concrete composite design in which concrete provides lateral restraint to steel plates against local buckling, and steel plates provide confinement to high-strength concrete. Design of Steel-Concrete Composite Structures Using High Strength Materials provides guidance on the design of composite steel-concrete structures using combined high-strength concretes and steels. The book includes a database of over 2,500 test results on composite columns to evaluate design methods, and presents calculations to determine critical parameters affecting the strength and ductility of high-strength composite columns. Finally, the book proposes design methods for axial-moment interaction curves in composite columns. This allows a unified approach to the design of columns with normal- and high-strength steel concrete materials. This book offers civil engineers, structural engineers, and researchers studying the mechanical performance of composite structures in the use of high-strength materials to design and construct advanced tall buildings. Presents the design and construction of composite structures using high-strength concrete and high-strength steel, complementing and extending Eurocode 4 standards Addresses a gap in design codes in the USA, China, Europe and Japan to cover composite structures using high-strength concrete and steel in a comprehensive way Gives insight into the design of concrete-filled steel tubes and concrete-encased steel members Suggests a unified approach to designing columns with normal- and high-strength steel and concrete

This book is the companion volume to Design Examples for High Strength Steel Reinforced Concrete Columns – A Eurocode 4 Approach. Guidance is much needed on the design of high strength steel reinforced concrete (SRC) columns beyond the remit of Eurocode 4. Given the much 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, there is a clear need for design beyond the guidelines. This book looks at the design of SRC columns using high strength concrete, high strength structural steel and high strength reinforcing steel materials – columns 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. The companion volume provides detailed worked examples on use of these high strength materials. This book is written primarily for structural engineers and designers who are familiar with basic EC4 design, and should also be useful to civil engineering undergraduate and graduate students who are studying composite steel concrete design and construction. Equations for design resistances are presented clearly so that they can be easily programmed into design spreadsheets for ease of use.

High Performance Concrete can be considered as a logical development of cement concrete in which the ingredients are proportioned and selected to contribute efficiently to the various properties of cement concrete in fresh as well as in hardened states. Higher strength is one of the features of High Performance Concrete which provides significant structural advantages. The three major components contributing to the cost of a structural member are concrete, steel reinforcement and formwork .This paper aims at comparing these major components when concrete of higher grade is used in the design and to establish that High strength concrete provides the most economical way for designing the load bearing members and to carry a vertical load to the building foundation through columns. The mix design variables affecting the concrete strength which are the most critical in the strength development of concrete includes water-cementitious material ratio, total cementitious material, cement-admixture ratio, amount of super plasticizer dose .These factors are to be analyzed in order to obtain a mix for concrete of higher grade. The design aid presently available gives design charts for design of members for concretegrade upto Fck=40N/mm2. Design curves for Fy=250N/mm2,415N/mm2 and Fck=60N/mm2, Fck=70N/mm2 using MATLAB have been drawn and given for aiding in the design of structures designed with these higher grade of concrete.

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
