4. CONCLUSION
Based on the findings of the limited specimens conducted in
the present investigation, the following conclusion can be
drawn as follows:
1. In case of failure mode, RC beams without any
strengthening, ductile flexure failure and concrete crushing at
compression zone were observed meanwhile there was no
shear crack has been observed.
2. Beam strengthened with NSM FRP bars mostly failed in
flexural after the longitudinal steel reinforcement yielded with
inclined cracks or splitting of the epoxy paste simultaneously.
No debonding of the NSM GFRP bars was observed.
Therefore, it shows that the load carrying capacity is totally
depends on the strength of concrete and FRP bars which are
fully utilized.
