Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

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 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous events have demonstrated the vulnerability of reinforced concrete infrastructure to blast loading. In buildings, ground-story columns are key structural components, and their failure can lead to extensive damages which can cause progressive collapse. To prevent such disasters, the steel reinforcement in such columns must be properly detailed to ensure sufficient strength and ductility. The use of modern concrete materials such ultra-high performance concrete (UHPC) is one potential solution to improve the blast performance of columns. UHPC shows high compressive strength, high tensile resistance and superior toughness, properties which make it ideal for use in the blast-resistant design of columns. The combined use of UHPC and high-performance steels can potentially be used to further enhance the blast resistance of columns. This thesis presents an experimental and analytical study which investigated the use of high-performance materials to increase the blast capacity and ductility of reinforced concrete columns. As part of the experimental study, a total of seventeen columns were tested under simulated blast loading using the University of Ottawa Shock-Tube. Parameters investigated included the effect of concrete type (NSC and UHPC), steel reinforcement type (normal-strength, high-strength or highly ductile), longitudinal reinforcement ratio, seismic detailing and fiber properties. The test program included two control specimens built with normal-strength concrete, five specimens built with UHPC in combination with high-strength steel, and ten columns built with highly ductile stainless steel reinforcement. Each column was subjected to a series of increasing blast pressures until failure. The performance of the columns is investigated by comparing the displacements, impulse capacity and secondary fragmentation resistance of the columns. The results show that using high-performance steels increases the blast performance of UHPC columns. The use of sufficient amounts of high-strength steel in combination with UHPC led to important increases in column blast capacity. The use of ductile stainless steel reinforcement allowed for important enhancements in column ductility, with an ability to prevent rupture of tension steel reinforcement. The study also shows that increasing the longitudinal reinforcement ratio is an effective means of increasing the blast resistance of UHPC columns The thesis also presents an extensive analytical study which aimed at predicting the response of the test columns using dynamic inelastic, single-degree-of-freedom (SDOF) analysis. A sensitivity analysis was also performed to examine the effect of various modelling parameters on the analytical predictions. Overall, it was shown that SDOF analysis could be used to predict the blast response of UHPC columns with reasonable accuracy. To further corroborate the results from the experimental study, the thesis also presents an analytical parametric study examining the blast performance of larger-scale columns. The results further demonstrate the benefits of using UHPC and high-performance steel reinforcement in columns subjected to blast loading.

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

This book was released on 2005 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents an experimental study of seven 2/3-scale specimens tested to investigate the behavior of joints between normal strength concrete floors intersecting high strength concrete columns. Two different loading scenarios were examined. Two new construction techniques were presented and their effects on the column overall capacity studied. The results show that casting a high strength core in the joint can restore virtually all the capacity of the high strength concrete column. Debonding the top flexural reinforcement of the floor where it passes through the joint reduces the impact of floor loading on the strength of the joint. Where the joint is made of normal strength concrete, the vertical strain in the joint at maximum concrete stress would be sufficient to develop high strength steel provided there is sufficient development of this steel in the column outside of the joint.
