| Sumario: | The long-term performance and corrosion fatigue damage status were investigated and analyzed under the service environment for the cable structures in cable-stayed bridges, suspension bridges, and suspender arch bridges. The artificial accelerated corrosion fatigue tests were carried out on galvanized parallel steel wire under coupled loading and environments. The damage mechanisms of galvanized parallel steel wire in corrosion, stress corrosion, and corrosion fatigue were investigated. The change laws of the mechanical properties of the cable were studied. Based on the image gray analysis, the evaluation method was proposed for the technical status of the damaged cable. Furthermore, combined with the cable damage evolution model, the service life prediction method and assessment technology of cables based on damage safety are established. |
