Abstract

In order to study the impact resistance of Seawater Sea-sand Concrete (SSC) beams reinforced with Basalt Fiber Reinforced Polymer (BFRP) bars, the impact responses of BRP-SSC beams with different reinforcement ratios (0.23%, 0.48%) and concretes strengths (30MPa, 50MPa) were tested by using a drop-hammer impact equipment under different impact energies (1818J, 2727J, 3636J, 4848J), and the residual load-carrying capacity of the beams was also tested after impact. The experimental results indicate that the failure mode of BFRP-SSC beam changes from bending failure to shear failure with the increase of impact energy, and the residual load-carrying capacity factor decreases gradually. Increasing reinforcement ratio or seawater sea-sand concrete strength can effectively decrease the maximum midspan deflection of the beams, and increase the initial peak impact force and impact resistance. This study can serve as important reference for the impact resistance design of the BFRP-SSC beam.
