| Abstract: | In the light of the current problem of poor durability of prestressing anchor systems for anchorage of suspension bridges in China,the authors in this paper put forward a kind of novel grease type corrosion resistant prestressing anchor system that has better durability,safety reliability and that is inspectable and replaceable.The novel anchor system has already been successfully used for anchorage of suspension bridges after the system underwent tests for static,dynamic loads,deformation,and workmanship of installation and replacing of grease and prestressing strands. |
