A research study of the impact testing of stainless steel reinforced concrete piers with different reinforcement ratios

Abstract

In this study, a domestically advanced super-high heavy-hammer impact test machine system was used to perform horizontal impact tests on five 1/5 reduced scale models of stainless steel reinforced concrete piers with different ratios of longitudinal reinforcements. The impact velocity and force of the ship model, displacement of the specimen measurement point, reinforcement strain, cracks, and ultrasonic velocity data during the impact process were collected and analysed. The results showed that, under these test conditions, the increase of reinforcement ratio can improve the lateral impact resistance of reinforced concrete piers to a certain extent.
