Impact tests are conducted on concrete beams prestressed with unbonded tendons using a drop-weight facility. These beams are measured comprehensively, including impact load-deformation histories, concrete and tendon strains, and beam cracking process. The interactions between the concrete beam and the tendons are thus systematically analyzed. A model that couples particle elements with finite difference approach (PEM-FDM) is also proposed to simulate the impact behavior of the complete system that is composed of concrete-tendon composites and t...
