Full TextAbstract
This paper discussed analytical and finite element (FE) studies on behavior of CFRP (Carbon Fiber Reinforced Polymer) strengthened reinforced concrete (RC) beams under pure torsion. Behavior of rectangular reinforced concrete beams strengthened with CFRP laminates under pure torsion was studied using finite element method by ABAQUS. Results were compared with the experimental data collected from previous studies. The finite element ultimate torsional capacity showed good agreement with the experimental results. In addition, the analytical methods suggested by fib Bulletin14 was used to predict value of effective CFRP strain and the torsional moment capacity. The difference between FE capacity of control and strengthened beams was less than 11%. The comparison between the design approaches suggested by fib Bulletin14 with previous experimental results discussed and compared.
