Findings of the global integrity check or observation of existing damage and
unwanted stay cable behavior can point to a need for investigation for local damage
detection.The local damage detection may focus on the anchorage zone as the most
critical component of the stay cables or the cable free length.An investigation of this
type utilizes techniques developed or tailored for stay cables along with other
customary inspection methods for bridges.Removing anchorage caps,use of visual
aids such as borescopes,cable dissection,material sampling and testing are some of
the means for damage detection in stay cables.Non-destructive techniques,such as
the use of ultra-sound,have been successful for detection of hidden damages and
flaws such as wire breaks and grout voids in the anchorage zones.New methods are
under investigation for damage detection along the free length of the cables.Once
the existing condition of stay cables is determined,instrumentation system can be
designed and installed for continuous health monitoring of the cables and the bridge.
Retrofitting and mitigation can be designed to address the problems identified
during the evaluation process.These include replacement of severely damaged cables
or strands,repair of guide pipes,concre+-cb encasement,cable cover pipe,grout voids,
and design and installation of vibration suppression devices (Telang et al.,2000).
