In high seismic intensity zones,the seismic safety of inland river wharves is crucial for the reliability and resilience of regional transportation networks.Taking the high-pile frame wharf of Gele Tourism & Passenger Center at Dongchuan Port as the research object,a three-dimensional finite element model considering soil-pile-structure interaction is established using OpenSees software.Combined with the results of site seismic safety evaluation,site-specific artificial ground motions are generated by the endurance time method for nonlinear dynamic time-history analysis.Based on structural characteristics and seismic codes,the maximum inter-story drift ratio and horizontal pile-head displacement are selected as key engineering demand parameters to establish a multi-level seismic performance evaluation framework.Seismic fragility analysis is conducted to derive exceedance probability curves for various damage states under different seismic intensities,so as to realize quantitative risk assessment of structural responses under frequent,design basis and rare earthquake levels.The results show that the endurance time method can efficiently simulate the whole evolution process of structural responses from minor to severe shaking.Both engineering demand parameters increase exponentially with ground motion intensity.The overall structure satisfies the seismic fortification target of “no damage under minor earthquakes,repairable damage under moderate earthquakes,no collapse under major earthquakes”,and exhibits favorable seismic performance.The research results can provide scientific basis and technical support for seismic design and performance evaluation of similar wharves
