Impact Test of GFRP Reinforced Bridge Barriers

This research will focus on the dynamic testing and analysis of GFRP reinforced concrete barrier walls. The pendulum impact test has been selected as the main approach due to its high cost-effectiveness. Researchers will construct segments of full-scale GFRP concrete barriers and test them under pendulum crush loading to evaluate the design. The impact energy coming from the kinetic motion and mass of the pendulum provides an efficient way of mimicking the vehicle impact loading exerted onto the concrete bridge barriers. From the test, the failure modes and details will be carefully examined and compared with the numerical modeling results building on Phase I activities to validate and improve the existing design. The expected outcome of this project will be a correlation between the GFRP reinforcement and impact resistance from the pendulum tests.
