Abstract：
A experimental study of flexural performance of reinforced concrete beams (RC) using prestressed aramid fiber reinforced plastic (AFRP) sheets with permanent anchor was conducted. The number of AFRP sheet layers on beams varied from 1 to 3 and the prestress level varied from 0.45 to 0.65. Based on the experimental study of seven beams, the beams strengthened with prestressed AFRP sheets were compared with the beams strengthened with un-prestressed AFRP sheets in flexural properties of cracking moment, yield moment, ulti-mate moment and flexural stiffness. The experimental results show that, compared with the un-strengthened control beams, the flexural performance of beams strengthened with un-prestressed AFRP sheets were enhanced, and that of beams strengthened with prestressed AFRP sheets were further improved, validating the efficiency of prestressed AFRP sheet retrofit.
