Abstract

This paper presents a parametric study on the pullout performance of twisted steel fibre in normal concrete. The twisted fibre is 40 mm long with a rectangular cross-section with a diagonal length of 1.12 mm. The experiment parameters include the number of twists (4 and 6) and the fibre inclination angle, θ, (30°, 45°, 60°, 75°, and 90°). The results indicate that the inclination angle has a great effect on the pullout response contrary to the number of twists. Such a database can then be employed to develop analytical models of the behaviour of Fibre Reinforced Concrete (FRC) elements (compressive, tensile, and flexural), facilitating the optimisation process of such elements and leading to optimum designs.
