SAFE LOAD CARRYING CAPACITY OFA SUSPENSION BRIDGEWITH DEGRADED CABLES

摘要

Recent suspension bridge cable evaluations haveutilized a sophisticated "Brittle Cable Model" todetermine the "Cable Safety Factor" of the degradedcables. This paper examines the analysis and designprocess of a suspension bridge, and the term "CableSafety Factor". To readily grasp the safe loadcarrying capacity of an existing suspension bridgewith degraded cables, the paper suggests analysiswith "Effective Area" approach and a safetydefinition using the cable wire proportional limitinstead of its ultimate strength.
