[IABSE 2018 Denmark] Optimal Maintenance of Suspension Bridge Cable Systems 2020-03-20
ÆÄÀϾÆÀÌÄÜ Ã·ºÎÆÄÀÏ :

Abstract

Suspension bridges are iconic, large, complex and unique structures with great public value. The 

main cables on suspension bridges are difficult to inspect and maintain and are virtually 

irreplaceable, although this has been done in two cases at extreme cost. Maintaining the main 

cables in an optimal manner is therefore of utmost importance. When developing an optimal 

maintenance strategy for the main cables, other related elements should be considered and 

included in the strategy, hence the entire cable system is the topic for this paper. Maintenance of 

the cable system is relatively expensive, but the costs can be minimized if an optimal maintenance 

strategy is developed and followed. The main goal of the maintenance strategy is to keep the 

bridge open at full traffic capacity at all times with the proper safety level and to do so at the 

lowest cost possible.


Keywords: suspension bridges; cable systems, maintenance strategy; LCC; dehumidification system.
