Bridges are critical components of the civil infrastructure and are normally designed for a long lifespan. The lifespan of suspension bridges depends on the health of their cables, which, in turn, is a function of many factors. Therefore, continuous structural health monitoring (SHM) and regular condition assessment of cables is highly desirable. In this article, some SHM procedures based on direct testing, indirect nondestructive testing and vibration theory are presented.
