This book was released on 1983 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The addition of steel fibers to concrete-type materials has been shown to improve many of the engineering properties of those materials. Notable among them is an enhancement in the tensile strength of an otherwise weak and brittle material. Although much is known about the tensile strength of steel-fiber reinforced concrete (SFRC) under one-dimensional state of stress, little is known with regard to the strength behavior under multi-dimensional tension-compression loading. This is attributed to a lack of suitable equipment for simultaneously applying tensile and compressive stresses. The research program described herein is focused on developing such equipment to study the behavior of SFRC under combined loadings. A review of the state-of-the-art research on the tensile strength of SFRC is given and a review of various methods of applying tensile stresses to concrete specimens is presented. The problem is to be overcome in applying a pure principal tensile stress are discussed.

This book was released on 1987 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes two phases of the research project. The first phase dealt with the strength and behavior of steel fiber reinforced concrete subjected to biaxial compression-tension loadings. A new piece of direct tension loading apparatus was designed and assembled for this study. Load history effects on the degradation of the tensile strength were also investigated. The second dealt with the modeling of a buried culvert system, both numerically and in the geotechnical centrifuge. The centrifuge test results were compared to the numerical analytical results to provide a validation of the numerical algorithm in which constitutive models could be incorporated.

Available in PDF, EPUB and Kindle. Book excerpt: Despite tremendous advances made in fracture mechanics of concrete in recent years, very little information has been available on the nature of fracture processes and on reliable test methods for determining parameters for the different models. Moreover, most texts on this topic discuss numerical modeling but fail to consider experimentation. This book fills these gaps and synthesizes progress in the field in a simple, straightforward manner geared to practical applications.

Available in PDF, EPUB and Kindle. Book excerpt: "In the research project presented in this PhD-thesis, an innovative type of fibre concrete is developed, with improved both the tensile strength and the ductility: the Hybrid-Fibre Concrete (HFC). The expression "Hybrid" refers to the "hybridisation" of fibres: short and long steel fibres were combined together in one concrete mixture. This is opposite to conventional steel fibre concretes, which contain only one type of fibre. The basic goal of combining short and long fibres is from one side to improve the tensile strength by the action of short fibres, and from the other side to improve the ductility by the action of long fibres." "In this research project, all important aspects needed for the development and application of Hybrid-Fibre Concrete have been considered. In total 15 mixtures, with different types and amounts of steel fibres were developed and tested in the fresh state (workability) as well as in the hardened state (uniaxial tensile tests, flexural tests, pullout tests of single fibres and compressive tests). A new analytical model for bridging of cracks by fibres was developed and successfully implemented for tensile softening response of HFC. At the end, the utilisation of HFC in the engineering practice was discussed, including a case-study on light prestressed long-span beams made of HFC."--BOOK JACKET.

Available in PDF, EPUB and Kindle. Book excerpt: The constitutive properties of steel fiber reinforced concrete (FRC) are being studied experimentally in a unique fluid cushion multiaxial cubical test cell at the University of Colorado. In the first phase of the program, the behavior of FRC was tested under three-dimensional compressive loading. The strength and stress-strain properties are analyzed by using constitutive models available in the literature. In the second phase, a modification to the existing test apparatus was made for testing cubical specimens under direct tension loading. The modification consists of brushes with individual bristles glued to the specimen. In this paper, results are shown from the biaxial tension-compression test program to demonstrate the strength interaction. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses design aspects of steel fiber-reinforced concrete (SFRC) members, including the behavior of the SFRC and its modeling. It also examines the effect of various parameters governing the response of SFRC members in detail. Unlike other publications available in the form of guidelines, which mainly describe design methods based on experimental results, it describes the basic concepts and principles of designing structural members using SFRC as a structural material, predominantly subjected to flexure and shear. Although applications to special structures, such as bridges, retaining walls, tanks and silos are not specifically covered, the fundamental design concepts remain the same and can easily be extended to these elements. It introduces the principles and related theories for predicting the role of steel fibers in reinforcing concrete members concisely and logically, and presents various material models to predict the response of SFRC members in detail. These are then gradually extended to develop an analytical flexural model for the analysis and design of SFRC members. The lack of such a discussion is a major hindrance to the adoption of SFRC as a structural material in routine design practice. This book helps users appraise the role of fiber as reinforcement in concrete members used alone and/or along with conventional rebars. Applications to singly and doubly reinforced beams and slabs are illustrated with examples, using both SFRC and conventional reinforced concrete as a structural material. The influence of the addition of steel fibers on various mechanical properties of the SFRC members is discussed in detail, which is invaluable in helping designers and engineers create optimum designs. Lastly, it describes the generally accepted methods for specifying the steel fibers at the site along with the SFRC mixing methods, storage and transport and explains in detail methods to validate the adopted design. This book is useful to practicing engineers, researchers, and students.

This book was released on 1981 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of the state-of-the-art research on steel fiber reinforced concrete (SFRC) is given and a review of the behavior and strength of plain concrete subjected to multiaxial stresses is presented. Two series of tests on SFRC were conducted. The first preliminary series, provides results of some basic tests on concrete randomly mixed with each of five types of commercially available steel fibers. This information allowed the determination of the optimum fiber to use in the second, final test series, where the properties of SFRC under three-dimensional compressive loadings are investigated. The conclusions drawn from the test results are that the addition of steel fibers to plain concrete increases the toughness, ductility and stiffness of the material. The greatest improvement of the tensile strength is provided by the longer fibers, whereas the opposite is true regarding the compressive strength. The reproducibility of the experimental results is good and the SFRC proved to be nearly isotropic as observed from the multiaxial tests.

This book was released on 2010-10-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is still the most widely used construction material since it has the lowest ratio between cost and strength as compared to other available materials. However, it has two undesirable properties, namely: low tensile strength and large brittleness that cause the collapse to occur shortly after the formation of the first crack. To improve these two negative properties and to achieve a partial substitute of conventional reinforcement, an addition of short discontinuous randomly oriented steel fibres can be practiced among others. In spite of positive properties, fibrous concrete did not find such acknowledgment and application as usual concrete. There do not still exist consistent dimensioning rules due to the lack sufficient large-scale static and dynamic experiments taking into account the effect of the fibre orientation. The intention of the book is twofold: first to summarize the most important mechanical and physical properties of steel-fibre-added concrete and reinforced concrete on the basis of numerous experiments described in the scientific literature, and second to describe a quasi-static fracture process at meso-scale both in plain concrete and fibrous concrete using a novel discrete lattice model. In 2D and 3D simulations of fibrous concrete specimens under uniaxial tension, the effect of the fibre volume, fibre distribution, fibre orientation, fibre length, fibrous bond strength and specimen size on both the stress-strain curve and fracture process was carefully analyzed.
