QUANTIFICATION OF SHEAR-STRENGTHENING EFFECT OF CONCRETE WITH CARBON FIBER SHEET BY PURE SHEARING EXPERIMENT

Abstract

The purpose of the present study is to obtain failure behavior and shear strengthening effect of concrete element with carbon fiber sheet. Firstly, newly middle size machine for strengthened concrete was developed by following the fundamental structure of the previous machine. The experimental parameters were mainly the angle of fiber to direction of principal stresses and elasticity of fiber. The experimental results present that the failure mode and the effect of shear strengthening concrete is different by arrangement of carbon fiber sheet.
