Abstract

Base on the existing condition that the bearing capacity is insufficient of some aging reinforced concrete (RC) members with axial tension, the formula for calculating the tensile capacity of the RC members strengthened with externally bonded carbon fiber reinforced plastic (CFRP) sheets is deduced and experiments of 8 RC members are conducted to examine the influences of CFRP sheets on the cracking load and ultimate load of the RC members. The calculation formulas agree with the experimental data and give the reference to the practical projects. The study is instructive and useful in strengthening of RC members with externally bonded CFRP sheets under axial tension.
