Flexural behavior of glass fiber reinforced polymer (GFRP) I-beam, GFRP and ultra-high strength fiber reinforced concrete (UFC) composite girders subjected to elevated temperature are described here. UFC slab was connected to the I-beam using FRP bolts and epoxy resin. Tests were carried out to investigate the mechanical properties of materials subjected to high temperature. Four point bending tests were carried out and the experiment results revealed the glass transition temperature of the shear connectors determined the failure criteria of the GFRP and UFC composite beams.
