Abstract

An experimental investigation program of RC tensile members strengthened with Carbon fiber sheets (CFS) was performed. The variables included types of CFS with both high strength and high modulus, different compression strengths of concrete, different layers of sheets, different steel ratios of rebars, and different thickness of concrete cover.<br>Consequently, it was evident that average crack spacing and crack width of CFS-strengthened RC members was much smaller than those of non-CFS. It was also discovered that the steel ratio of rebars, the thickness of concrete cover had the less influence on the crack behavior due to the dominated constraining effect of CFS.<br>In addition, tension-stiffening effect of RC members with CFS was calculated. The comparison between the calculation and experimental results was conducted.
