Seismic fragility analysis of concrete pile-supported wharves based on single-degree-of-freedom model

Abstract

Article Highlights The pile-supported wharf can be represented by an equivalent single-degree-of-freedom model for seismic demand analysis. The trilinear backbone curve and Pivot hysteresis rule can mimic the restoring force characteristics of wharf well. The fragility curves developed by the single-degree-of-freedom model have little difference with those of actual wharf.
