| Summary: | This paper presents experimental and analytical study related to the flexural
behavior of concrete beams longitudinally reinforced with GFRP bars. The specimens
consist of simply supported reinforced concrete beams with two point load. Totally 16
concrete beams includes 8 beams reinforced with steel and 8 beams reinforced with
GFRP bars were tested to failure. Flexural capacity of the beam was observed
experimentally and analytically. A computer program of cross sectional analysis using
discrete element model was developed in this study to determine the flexural capacity of
the beams. In addition, available stress-strain model proposed by the other researchers
was used in order to simulate the behavior of material in calculation process. Finally, the
flexural capacity obtained from analytical calculation was compared to that obtained
from the test in term of moment-curvature curves and load deflection curves. The results
show that beam reinforced with GFRP experienced larger ultimate load and larger
deflection at same load level compared to beam reinforced with steel.
