The emerging strengthening technology of high strength steel wire mesh and high performance mortar is widely used in the field of seismic strengthening, bending and shear strengthening, and reinforcement of beam-column connections in China. In this paper, through the experimental research on impact and flexural behavior of RC beams strengthened with high strength steel wire mesh and high performance mortar, two different stress responses under different stress modes were evaluated. Drop hammer impact test was conducted on the B1 beam and static loading test was conducted on the B2 beam. Through the analysis of the failure mode, the strain of the steel and the mortar, and the change of deflection under different loading conditions, the difference was obtained under the two loading modes. The results showed that the beam, under the impact, resisted the instantaneous impact load, which reached the maximum quickly and then rapidly decreased to the minimum. The transfer of the impact energy was slightly slower than the change of the load. Additionally, the structure deformation of the beam under the static loading increased with the increasing load.
