Flexural behavior and serviceability performance of 24 full-scale concrete beams reinforced
with carbon-, glass-, and aramid-fiber-reinforced-polymer (FRP) bars are investigated. The
beams were 3,300 mm long with a rectangular cross section of 200 mm in width and 300
mm in depth. Sixteen beams were reinforced with carbon-FRP bars, four beams were
reinforced with glass-FRP bars, two beams were reinforced with aramid-FRP bars, and two
were reinforced with steel, serving as control specimens. Two types of FRP bars with
