Damage evolution of\r\nelasto-plastic circular steel piles and reinforced concrete (RC) one with cracking and yield of reinforcement are focused on, and the failure patterns and residual damages are captured by the proposed constitutive models. The superstructure excitation behind quay wall is\r\nreproduced as well.","references":"[1] Hamada, M.(1992). \"Large ground deformations and their effects on lifelines: 1964Niigata earthquake.
