Time-variant probabilistic evaluation method for parallel wire cables throughout the lifetime
Under the combined effects of service environment,internal material factors,and external loads,the resistance of cable structures declines over time,shortening their service life.To conduct a long-term assessment and propose effective maintenance measures for suspension cables,this paper presents a time-variant probabilistic evaluation method for parallel wire cables.This method considers the service environment,internal material factors,and changes in external loads.The impact of these factors on the service life and reliability of suspension cables throughout their service period is analyzed.Additionally,based on the trends in cable reliability,the paper considers the positive effects of differ-ent maintenance measures on extending the service life.The effect of timing and duration of mainte-nance interventions is discussed,providing data support for the maintenance strategies of cable struc-tures.
