STUDY ON AXIAL TENSILE BEHABIOR OF HIGH PERFORMANCE FIBER REINFORCED MORTAR WITH REINFORCING BAR

Abstract

  This Paper presents experimental and numerical results on axial tensile tests of prism members with HPFRM (High Performance Fiber Reinforced Mortar) and conventional reinforcing bar. With increasing fiber content in the HPFRM, the tension stiffening effect was improved as well as cracks being distributed with finer crack width. In addition the orientation of the fibers affected both the tension stiffening and the crack distribution. To evaluate these structural behaviors the analytical simulation using 2D Rigid Body Spring Model was applied with some improvements on the material constitutive law for unique characteristics on the HPFRM.
