| Abstract: | By full-scale model test of the anchorage zone of the pylon of Runyang Yangtze River Bridge,the prestressing technique for the U-shaped tendons was investigated,and the stress distribution in the model were measured and analyzed,and the critical cracking load and ultimate load for the anchorage zone were obtained.The model test was characterized in the aspect of emulating the cable-action by diagonal loading facility,measuring the sheath friction by an auxiliary model,and distributing the stress sensors throughout the model. |
