Abstract

High Performance Fiber Reinforced Concrete (HPFRC), which has a high compressive strength of about 130 N/mm2 and a high tensile ductility by the addition of short steel fibers, was used in this study. Axial tensile tests on reinforced HPFRC members were conducted in order to investigate the influence of fibers on tension stiffening. Therefore the fiber content and the dimensions of the fibers (aspect ratio) were varied in the HPFRC mixture . The average concrete stresses, which were derived from the test results after correction for the initial shrinkage strain, showed that an increase e of the fiber content and a larger aspect ratio lead to a higher tension stiffening. Moreover, a simplified equation to determine the tension stiffening in HPFRC was proposed on the basis of the axial tensile test results.
