Coastal bridges exposed to the marine environment always suffer from non-uniform corrosion along the pier height. As the non-uniform corrosion increase, the material properties of the pier in the splash and tidal zone deteriorates significantly, affecting the seismic performance of the pier. In this study, four scaled bridge pier specimens were designed and fabricated. These specimens were subjected to different level of electrical accelerated corrosion in the proposed splash and tidal zone. Then, the cyclic load tests were conducted on the four bridge pier specimens. The hysteretic behavior, loading capacity, ductility, energy dissipation capacity and mean curvature of each specimen were analyzed. It was found that with increasing corrosion level, the load capacity, ductility and cumulative energy consumption of the specimens decreased. When the corrosion was severe enough, the location of the plastic hinge will transfer from the pier bottom to the corroded zone.

暴露在海洋环境中的沿海桥梁总是沿码头高度遭受非均匀腐蚀。随着不均匀腐蚀的增加，飞溅和潮汐带中墩的材料性能显着下降，从而影响了墩的抗震性能。在这项研究中，设计和制造了四个比例尺的桥墩标本。这些标本在拟议的飞溅和潮汐带中经受了不同程度的电加速腐蚀。然后，对四个桥墩标本进行了循环荷载测试。分析了每个样品的磁滞行为，载荷能力，延性，能量耗散能力和平均曲率。发现随着腐蚀水平的提高，试样的承载能力，延展性和累积能量消耗降低。
