Behavior Analysis of Looped Prestressed Tendons in Different Penetrating Strands Technology

Luo, Jia Yi / Zhang, Xie Dong / Guo, Xing Mao

At present, small radius looped prestressed tendons have been widely used in cable-stayed bridge anchorages; the error limitation of stretch elongation in prestressed technology is 6 percentage, but in field it always exceeds the limitation. In this study, the main factors which lead to the stretch elongation were analyzed through a field full-size model test of a cable-stayed bridge. Moreover, the behaviors of ring prestressed tendons were studied for different penetrating strands technology and some advices and suggestions were finally made to offer an example for similar engineering.
