Abstract—An experimental study has been carried out to
investigate the structural behavior of beam which was
strengthened by glass fiber reinforced polymer (GFRP-S). The
Experimental was carried out to determine the effect of fatigue
loads on flexural capacity of reinforced concrete beams. Each
specimen was 6 m long with 300x500 mm rectangular cross
section. Each specimen was treated with different loads. In this
study using two different loads applied to the beam was static
loads and fatigue loads. Static load was applied to the beam (B1)
without GFRP reinforcement, a beam control. (A2) applied
static load beam with GFRP reinforcement. Fatigue load
applied to the beam reinforced with GFRP (B2) as well. For (A1)
beam load was applied to the ultimate strength after reached
51.84 kN load, and then the concrete beams was strengthened
with GFRP and fatigue loading until crushed. The result of this
research showed that deflection under fatigue loads was higher
than deflection of static loads. GFRP reinforcement showed an
increase in the capacity of the test beam. The Increase of the
power of static loading with GFRP reinforcement of 4.4%. The
increase in the fatigue strength of 75 kN was 4.7%, the
imposition 167.5 kN was 4.2%, and the imposition 260 kN was
2.9%.
