| Research Abstract |
Basalt fiber reinforced polymers (BFRP) and piano wires are considered in the hybridization in order to realize high performances in stiffness, strength, and ductility. It is confirmed that the bond strengths at epoxy putty-concrete interface and at polymer cement mortar and FRP are not so high, but a good bonding can be realized between concrete and polymer cement mortar and between epoxy putty and FRP. The structural performances of RC beams strengthened can be enhanced largely with prestressed FRP An analytical study is also performed in order to investigate the flexural behavior of RC beams strengthened with prestressed FRP.
