Abstract:

Cable systems of a cable-stayed bridge consist of cable and cable anchorage. Cable tension caused by prestress, dead load, and live load acts directly on the cable anchorage. In addition to direct tension, bending deformation caused by live load, temperature changes, and wind load act on the anchored stay cables. Furthermore, wind-induced oscillations may be considered. Because the cable tension and bending deformation occur repeatedly, it is necessary to verify fatigue behavior. The structural details of cable anchorages are complex, making it difficult to evaluate their fatigue resistance. Therefore, fatigue tests were conducted on full-scale specimens that include proposed anchorages and cables to examine their performance. The obtained results show that fatigue cracks initiated at the welded toe of the bearing plate to anchor web plates were caused by plate bending; therefore, some refinements of structural details are necessary. The bending fatigue strength of semi-parallel wire cables socketed by two types of anchorage were both proved to be sufficient for use as stay cables for an 870-m span cable-stayed bridge.
