The Research of Application of the Looped Prestressed Tendons with Large Tonnage and Small Radius in the Anchorage Zone of Cable-stayed Bridge Tower

Nowadays the large tonnage and small radius annular prestress system are applied in the anchorage region of large span cable stayed bridge construction in our country. The application of this system has been a breakthrough of the Design Specification of Highway Bridge and Culvert. In this article, the application of this system applied in the anchorage region of cable stayed bridge tower has been probed in close connection with the full scale model test of the anchorage zone of the Wuhan Junshan Changjiang River Bridge.
