Measurement of Average Tensile Force for Individual Steel Fiber Using New Direct Tension Test



The use of steel-fiber reinforcement as an alternative to conventional reinforcement of various concrete structures has been limited in the construction industry. This is because of the fact that, unlike traditional reinforcement, the performance characterization of steel-fiber concrete is not standardized, because the fibers are distributed throughout the concrete section. Whereas direct tensile resistance is the performance measurement required for design, the steel-fiber industry has yet to actively employ direct tensile testing of steel fibers. The tensile response of steel-fiber-reinforced concrete has been investigated. The primary purpose of this paper is to present a robust new direct tension test method. This method is able to determine the uniaxial tensile response of steel-fiber-reinforced concrete. The method uses a three-dimensional “hourglass”-shaped tapered specimen. This paper also focuses on developing a practical method to determine the average tensile force per fiber.
