Since the late 1980s, cable-strut system bridges, including suspender bridges, cable-stayed bridges, and arch bridges, have been extensively constructed due to advancements in cable material technology. These structures are favored for their lightweight design, large spans, high navigational clearance and economic benefits. The stay cables or suspenders serve as critical components for force transmission in these bridges, and their safety and durability are paramount for the proper functioning of the structure. Unfortuantely, operational and environmental factors can lead to corrosion and fatigue damage in the cable systems, occasionally necessitating premature repairs or replacements of multiple cables or suspenders. To monitor and detect changes in the cable-strut system and mitigate potential damage, various protective measures and damage monitoring technologies have been proposed to ensure the safety of cable-strut system bridges. This paper first presents the types of cable damage and analyzes the mechanisms behind their formation, followed by a summary of the available detection technologies that have been implemented in practice.
