The Structural Expertise of Steel Cables

Ludovic G. Kopenetz, Ferdinand-Zsongor Gobesz

Abstract


Considering the fact, that steel cables are structural elements forming statically determinated systems, their rupture can lead to catastrophe. In  this context, thestructural assessment of steel cables represents a  primary necessity, generated bythe requirement to assure security and safety in use.
Generally the main causes which induce degradation/deterioration of cables are: fatigue and corrosion.
The effects of corrosion and fatigue are displayed usually through fiber laceration sequent to a certain service time, after which the number of ruptures and lacerations increases exponentially.
This paper covers some problems of structural expertise along with numerical simulation aspects of corrosion and fatigue, as well as a methodology for the deduction of the presumed service life of steel cables.
