An experimental study of impact performance of RC piers with different reinforcement ratios

Abstract

The most advanced domestic super-high drop hammer impact test system was used in this study to simulate ship-piers collisions. The main focus of this study was to examine the impact forces, displacements, and strain time histories of five reinforced concrete pier specimens with different reinforcement ratios, and to analyse concrete damage and crack propagation and development after impact events. The results showed that, under this test conditions, an increase in reinforcement ratio can somewhat improve the lateral impact resistance of reinforced concrete piers.
