To study the reinforcement effect of textile-reinforced concrete (TRC) on concrete structures in a marine environment, a four-point bending loading method was used for graded loading to analyze the influence of the dry–wet cycle number, the reinforcement method, and chopped fiber addition on the flexural properties of load-holding reinforced concrete beams reinforced with textile-reinforced concrete. The results show that with the increase of dry–wet cycle numbers, the crack width and deflection of beams develop faster and the bearing capacity decreases. The performance of the prefabricated textile-reinforced concrete plate is close to that of a cast-in-place textile-reinforced concrete in limiting crack, bearing capacity, and deflection deformation. The addition of chopped fibers in fine-grained concrete can improve the reinforcement effect of textile-reinforced concrete. Based on the experimental results and referring to the relevant design codes and literature, the calculation formula of the bearing capacity of TRC-strengthened beam with a secondary load is established, and the calculated values are in good agreement with the actual values.

Rate Effects

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.
