“…Accordingly, the same trend was also found on SNFRC [6]. Also, this flatter post-peak softening branch behaved on the relatively same pattern due to the combination of discrete steel or synthetic fibers and reduced transverse steel confinement.…”

“…The short and discrete fibers in the concrete mixture modify its typical brittle response to a significant increase in ductility about the no fiber concrete. Furthermore, a previous study has shown that SNFRC could improve the post-peak behavior, ductility, and energy dissipation ability of concrete elements under axial load [6]. It has proven that the combination of synthetic fibers and transverse steel confinement could reduce the amount of confining reinforcement and still behaved in ductile response [6].…”

Abstract. Many empirical confinement models for normal and high strength concrete have been developed. Nevertheless, reported studies in the term of confinement of fiber reinforced concrete are limited. Whereas, the use of fiber reinforced concrete in structural elements has become the subject of the research and has indicated positive experiences. Since the stress-strain relationship of concrete in compression is required for analysis of structural members, the study of the stress-strain relationship for synthetic fiber reinforced concrete is substantial. The aim of the study is to examine the capabilities of the various models available in the literature to predict the actual experimental behavior of synthetic fiber reinforced highstrength concrete columns. The experimental data used are the results of the circular column specimens with the spiral spacing and the volume fraction of synthetic fiber as the test variables. The axial stress-strain curves from the tests are then compared with the various models of confinement from the literature. The performance index of each model is measured by using the coefficient of variation (COV) concept of stress and strain behavior parameter. Among the confinement models, Cusson model shows the closest valid value of the coefficient of variation.
