Abstract

In this study, in order to examine the impact properties of a stainless steel reinforced concrete bridge pier under the conditions of horizontal impact load effects, a multifunction ultrahigh heavy drop hammer impact test system was utilized. The stainless steel reinforced concrete bridge piers had different impact energies, and the impact force time-history, displacement time-history, and strain time-history curves, as well as the crack developing state, were obtained during the testing. The test results showed that the peak values of the impact force, strain, and displacement increased with the increase of the impact energy under the impact load, and the fluctuation frequency also increased. The crack development was mainly concentrated in the lower frontal section of the bridge pier, as well as the middle and lower sections of the back of the bridge pier.
