- Abstract
The domestically most advanced ultrahigh drop-hammer impact test system was used to simulate the ship-bridge collision under the impact load effect of horizontal collision. In accordance with the similarity principle, 4 reinforced concrete bridge pier specimens were fabricated according to the proportion of 1:5, and closed-cell foam aluminum buffer material with different thicknesses and densities was designed at the impact cart head to study the influence of closed-cell foam aluminum buffer material on the damage performance of reinforced concrete bridge pier specimen. The result showed that, after multiple impacts on the reinforced concrete bridge pier specimens with the same energy, the specimens using closed-cell foam aluminum as the buffer material had a smaller crack width and damage factor than the specimens without using it; under the low-energy impact effect, the buffer effect of closed-cell foam aluminum was not obvious; under the high-energy impact effect, the buffer effect of closed-cell foam aluminum was relatively obvious, and the scheme of doubling the density of closed-cell foam aluminum had a better buffer effect than the scheme of doubling the thickness.
