Abstract
Application of High Strength Concrete (HSC) in RC structures requires the knowledge of its mechanical properties and of its design implications. In certain cases the brittle nature of HSC requires the inclusion of steel fibers in the mixture, which also influence other material properties. The current study focuses on bondslip behavior of deformed steel bars in normal and in high strength concrete (NSC and HSC), with and without fibers. This paper describes the first stage of the study, which consists of pullout tests of deformed steel bars of different diameters from large cylindrical specimens made of NSC and HSC. Half of the NSC and HSC specimens included 30-mm hooked-end steel fibers that were given in a constant volume ratio of 0.75%. The paper describes the tests and their results, and points out the conclusions regarding the influence of concrete strength and the inclusion of fibers on the bond-slip behavior of deformed steel.
