EFFECT OF THE CYCLIC FRICTION ON THE LIFE OF CABLES EMPLOYED ON CIVIL ENGINEERING STRUCTURES

EFFET DES FROTTEMENTS CYCLIQUES SUR LA DUREE DE VIE DES CABLES POUR OUVRAGES D'ART

The steel cables used on civil engineering structures are subjected to various loads and cyclic deformations which result in random, small amplitude displacements between their components parts (individual wires) and/or between the cables and associated accessories (anchoring pieces, saddles, clamps). The cyclic displacements result in friction or fretting between the surfaces that are in physical contact and consequent wear, cracking or breaking of the wires making up the cables. A study of the behaviour of certain pairs of materials (iron-zinc, iron-aluminium and iron-polyethylene) shows that it is possible to delay the appearance of faults in the wires by ensuring that the contacts between the surfaces are supplied with the debris produced by the friction or by "cancelling out" the frictional forces.
