Development of a Simple Fatigue Resistant Stay Cable Anchorage
A simple fatigue-resistant anchorage for seven wire prestressing strand was developed and studied. The fatigue test results indicate that an anchorage incorporating copper or aluminum wedges which have been formed to match the strand produce an anchorage which can attain the fatigue strength of the strand. The fatigue test results were correlated with load distribution measurements, finite element analysis, electron microscopy of the fractures, and various wear models. A clear understanding of the factors relating to the fatigue performance of the wedges studies resulted from the correlation of the various studies. A further optimization of the anchorage is possible based on the results of the theoretical studies. However, the anchorage as developed using copper wedges is adequate. The developed anchorage provides a simple anchorage which allows for individual insertion and removal of the strands making up a cable stay.
