Book Local Bond Stress slip Relationship of Reinforcing Bars Embedded in Fiber Reinforced Concrete Under Splitting Type Failure

Download or read book Local Bond Stress slip Relationship of Reinforcing Bars Embedded in Fiber Reinforced Concrete Under Splitting Type Failure written by Walid Jalkh and published by . This book was released on 1993 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study summarizes experimental results of the local bond stress-slip response of reinforcing bars embedded in fiber reinforced concrete (FRC) under splitting type failure. Pullout specimens were tested to study the effect of several parameters, namely, type, volume fraction, and aspect ratio of fibers, concrete cover to reinforcing bars (or splitting area surrounding the reinforcing bar), and size of reinforcing bar. The experimental results showed that the major contribution of fibers is in the post-splitting range. As compared to plain concrete, the bond behavior of fiber reinforced concrete is more ductile inasmuch as the post-splitting bond stresses are increased. This increase is function of the fiber reinforcing index and of the fiber bond characteristics. The results from the current study were combined with other results reported in technical literature and used to develop a model to describe the bond stress-slip relationship of reinforcing bars embedded in plain and FRC under splitting type failure. The model accounts for all of the important parameters that tend to influence the bond characteristics of reinforcing bar3 as observed in the experiment. It should be mentioned that this study consists the second pact of a two-phase experimental program dealing with the local bond stress-slip characteristics of reinforcing bars embedded in fiber reinforced concrete. While this current phase concentrates on the splitting type of failure, the first part of the study (Ref. 4) emphasized pullout failure.

Book Local Bond Stress slip Behavior of Reinforcing Bars Embedded in Fiber Reinforced Concrete

Download or read book Local Bond Stress slip Behavior of Reinforcing Bars Embedded in Fiber Reinforced Concrete written by Marwan Mohamed Hout and published by . This book was released on 1992 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study summarizes experimental results of the local bond stress-slip relationship of reinforcing bars embedded in fiber reinforced concrete (FRC). More than 70 bond specimens were tested and the effect of several parameters on the local bond stress-slip behavior was investigated. These include, size of reinforcing bar (#6 and #8); type of fibers (hooked steel, polypropylene); volume fraction of fibers Vf (between 0.9% and 1.4ft for the steel fibers, 1.5% for the polypropylene fibers); type of specimen (pullout, beam); and confinement (confined, unconfined). Whereas the primary emphasis was on the monotonic local bond stres3-slip response, some specimens were tested under large slip reversals to study the effect of fibers on the cyclic bond stress-slip behavior. The results showed that the addition of fibers to concrete matrixes improves the bond characteristics of ordinary reinforcing bar3. For specimens in which bond failure was by pull-out, adding steel fibers in 2% by volume fraction increased the maximum local bond resistance by about 15%. However, the intrinsic shape of the local bond stre33-slip behavior does not change in comparison with conventional concrete. Furthermore, the addition of fibers to concrete matrixes does not seem to influence the stiffness degradation characteristics of the local bond stress-slip response under cyclic 1oading compared to conventiona1 confined concrete reported in technical literature.

Book fib Model Code for Concrete Structures 2010

Download or read book fib Model Code for Concrete Structures 2010 written by fib - federation internationale du beton and published by John Wiley & Sons. This book was released on 2013-12-04 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Federation for Structural Concrete (fib) is a pre-normative organization. 'Pre-normative' implies pioneering work in codification. This work has now been realized with the fib Model Code 2010. The objectives of the fib Model Code 2010 are to serve as a basis for future codes for concrete structures, and present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. The fib Model Code 2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement. It is expected to become an important document for both national and international code committees, practitioners and researchers. The fib Model Code 2010 was produced during the last ten years through an exceptional effort by Joost Walraven (Convener; Delft University of Technology, The Netherlands), Agnieszka Bigaj-van Vliet (Technical Secretary; TNO Built Environment and Geosciences, The Netherlands) as well as experts out of 44 countries from five continents.

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Size Effects on Bond slip of Reinforced Concrete Connections

Download or read book Size Effects on Bond slip of Reinforced Concrete Connections written by Jongmin Seo and published by . This book was released on 2011 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: When reinforced concrete structure is subjected to earthquake loads, cracks will inevitably appear. A bond-slip occurs where cracks have developed. The influence of the bond-slip is not negligible on the lateral behavior of structures. Researchers have studied the bond-slip for the past four decades. Most studies investigated a relationship of the bond stress-slip experimentally and developed empirical equations. Among them, the equation developed by Ciampi et.al. (1981) has been widely used in design practice. Some earlier studies investigated each failure mode (Debonding or splitting failure) analytically without considering size effects. Other researchers studied the size effects on the bond-slip through experiments only. Design codes (ACI building codes and AASHTO bridge specifications) consider the size effects on the bond-slip by increasing the development length as the size of rebars increases. In this study, the size effects on the bond-slip are explored by analytical model developed herein, which is called SHC (Stacked Hollow Cone) model, in conjunction with CVBCM (Complex Variable Boundary Collocation Method). The governing failure mode and the maximum force with corresponding bond-slip at failure state can be predicted under various geometric conditions by this model. This analytical model provides a better understanding of the size effects on complicated bond-slip problems and predictions of the lateral behavior of a column become more accurate when the bond-slip is considered.
