| Abstract: | Taking the cable-stayed bridge of Shanghai Changjiang River Bridge as the research object,the typical cable-to-girder anchorage zone of the bridge was selected and the full-scale model test for the fatigue of the anchorage zone was made to investigate the relevant plates in which the fatigue failure would possibly occur,the stress and stress distribution in the critical parts and to observe the locations where the fatigue cracks would appear and the propagation laws of the cracks.The results of the investig... |
