In this paper, numerical simulation on fireproof behavior of RC beam strengthened by SMPM is carried out with ABAQUS program, in which the coupled process of temperature and displacement is fully considered, and the real circumstance of fire exposing in a large stove is reproduced. The calculating formulas of thermal conductivity and specific heat capacity are proposed by analyzing the thermophysical characteristics of the polymer mortar. Variations in deflection at span center and section temperature of the strengthened beam under standard temperature-time curve is also simulated. Variation in section temperature of beam in calculation is closely matched to the test. Deflections of span center in both experiment and numerical simulation reach to 190mm when fire loading lasts 120min, which is below the maximum allowance limit regulated by Fireproof Code of Buildings (L/20, 255mm for the beam). Therefore, the new strengthening method can satisfy fireproof requirement no need to take any other measures.
