Book Design of High Strength Steel Reinforced Concrete Columns

Download or read book Design of High Strength Steel Reinforced Concrete Columns written by Sing-Ping Chiew and published by CRC Press. This book was released on 2018-04-17 with total page 104 pages. 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.

This book was released on 2018-04-17 with total page 96 pages. Available in PDF, EPUB and Kindle. 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.

Book Strength of High Strength Concrete Columns Under Eccentric Compression

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.

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 Performance of Full scale Ultra high Performance Fiber reinforced Concrete Column Subjected to Extreme Earthquake type Loading and Effect of Surface Preparation on the Cohesion and Friction Factors of the AASHTO Interface Shear Equation

Download or read book Performance of Full scale Ultra high Performance Fiber reinforced Concrete Column Subjected to Extreme Earthquake type Loading and Effect of Surface Preparation on the Cohesion and Friction Factors of the AASHTO Interface Shear Equation written by Guillermo Palacios and published by . This book was released on 2015 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buildings in areas of high seismicity may be subjected to large axial stresses as well as severe earthquake loading. In order to protect the integrity of these buildings, concrete columns must possess high compressive strength and adequate ductility. While the use of high strength concrete (HSC) may appear as an attractive alternative and can reduce the section size of first story columns, its increase in strength leads to an increase in brittleness compared to that of normal strength concrete. For that reason, HSC requires a large amount of transverse reinforcement to maintain adequate ductility, which leads to severe congestion in placement of the reinforcing bars and adds to the cost and effort. A solution may be found in ultra-high-performance fiber-reinforced concrete (UHPFRC). UHP-FRC is an innovative material which provides high compressive strength (25- 30 ksi) and shear strength as well as improved compressive ductility and excellent confinement characteristics. The addition of high strength steel microfibers into the high strength concrete mix can reduce the need for excessive transverse reinforcement. The UHP-FRC mixture used in this research was created to maximize the dense particle packing concept, and it is essentially self-consolidating. Even though UHP-FRC provides superior material properties, there is limited test data available on its full-scale structural application. The performance of full-scale modern high-rise moment frame columns, with both normal strength concrete and UHP-FRC, tested under very large cyclic displacement reversals up to collapse is presented and discussed in the first part of this thesis. The use of UHP-FRC completely changes the typical failure mode of concrete columns as it improves confinement and prevents concrete crushing. Experimental results showed that the UHP-FRC column exhibited higher peak strength and greater drift capacity before succumbing to significant strength degradation compared to a conventional normal strength reinforced concrete column. The achievement of composite action of concrete bridge deck systems relies heavily on the bond between the precast beams and the cast in-place concrete slabs. Two important components responsible for resisting horizontal shear are the cohesion and/or aggregate interlock, and the friction between the crack faces. The second part of this thesis investigates the influence of surface preparation on the cohesion and friction factors of the nominal interface shear resistance equation of the AASHTO LRFD Bridge Design Specifications (2014). A systematic surface preparation method was developed to recreate the different International Concrete Repair Institute (ICRI) Concrete Surface Profiles (CSPs) from which a series of push-off tests were performed to assess the contribution of the cohesion factor and the friction factor used in the AASHTO interface shear equation. An experimental program was developed made up of component pushoff tests and full-scale composite box and slab beam tests. The experimental results suggest that the cohesion factor used by AASHTO may be considered un-conservative as both the cohesion factor and friction factor are not only dependent on the surface roughness, but also can be limited by the strength of the concrete matrix. The effect of a smoother surface finish typically formed with the use of SCC was also investigated in the full-scale specimens.
