The strain-rate effects of reinforced concrete beams are studied in this paper. Considering the strain-rate effects of structural material, dynamic responses of reinforced concrete beams subjected to monotonic loading and cyclic loading at different loading rates that might be experienced during earthquakes are simulated using the nonlinear finite element program ABAQUS. The influences of loading rate on loading capability and failure mode of reinforced concrete beams are investigated. The results show that as the loading rate increases, the loading capability increases, the increment is associated with the shear span ratio and loading mode. The increment at cyclic loading is smaller than that at monotonic loading; as the shear span ratio changes, the failure mode changes, the increment changes; the failure mode has nothing to do with the loading rate.
