000012204 520__ $$2eng$$aRehabilitation with SMPM (high-strength steel wire mesh and polymer mortar) is a new technique of structural strengthening. As a new technique of strengthening, it has a series of obvious advantages. Experiments were conducted to investigate the flexural behavior of 3 RC beams. BF-1 is a comparative beam which is not on fire, BFF-1 is a comparative one fire-exposed, and BFF-2 is a strengthened specimen after fire. The Experimental results showed that the flexural load-carrying capacity and stiffness of the fire-exposed RC beam were reduced. In the fire-exposed course, temperatures of steel and concrete were not measured. The temperature distribution of the beam is calculated by thermal analysis with ANSYS procedure. The flexural load-carrying capacity and stiffness of the strengthened beam were increased effectively. The effect of this rehabilitation can reach the level of RC beams before fire on load-carrying capacity. Based on the tests and analyses results, the design formulae of the flexural load-carrying capacity and stiffness were supposed. The calculated results are in good agreement with the experimental ones.
