The experimental results show that: the failure mode of strengthened beam at elevated temperature can be classified as flexure failure mode or flexure-shear failure mode, and the failure mode of strengthened beam at high temperature may be different from that at room temperature; and although the load supported by the strengthened specimen is larger than that supported by the unstrengthened specimen, the fire resistance of the strengthened specimen is still larger than that of the unstrengthened specimen, due to the influence of fire insulation.

Test results show that (1) the failure modes of the strengthened beams at high temperature can be classified as a flexure failure mode and a flexure-shear one;(2) the flexure failure of the strengthened beams at room temperature may change at high temperature;(3) as compared with the unstrengthened beam, the strengthened beams with higher load are of stronger fire resistance due to the existence of fire coating; and (4) the increase of the strengthening ratio may result in the improvement of fire resistance and the change of failure mode.
