| description | Fiber reinforced polymers (FRP) have been increasingly used over the past few
decades in a variety of structures and have become a popular alternative in
construction world. It is one of the effective techniques for strengthening and
repairing the reinforced concrete (RC) beams under flexural loads. The bond strength
is a fundamental aspect of the structural behavior, since the performances of the
concrete-reinforcement system depends on the interface. This study focused on the
effect of surface preparation on bonding performances of beam strengthened with
GFRP plate. Three beams with the dimensions of 1 00 mm x 200 mm x 1500 mm were
subjected to four-point flexural loading test. One beam was considered as
unstrengthened control beam, the second beam and the third beam were tested under two
different surface preparations which are rough (groove) surface and smooth surface.
Experimental data on load, deflection, strain and failure modes of each of the beams were
obtained and compared based on the GFRP as the strengthening material. The results
indicated that rough (groove) surface preparation increased the ultimate strength of FRP
strengthened beams compared to the smooth surface and unstrengthened beams. |
