Abstract
This paper represents a tension stiffening effect on a High Performance Fiber Reinforced Mortar (HPFRM), which has a compressive strength of 130 N/mm2 and high tensile ductility by the addition of short steel fibers. Uni-axial tensile tests on the reinforced HPFRM with various fiber content and fiber orientation were conducted. On basis of the experimental results and the analytical simulations using Rigid Body Spring Model (RBSM), a simplified equation to determine the tension stiffening effect on the HPFRM was proposed. The accuracy of the model was verified through simulations with non-liner FEM analyses on reinforced HPFRM members.
