Book Description
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 Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, 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 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 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 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
