| Abstract: | Prestressed concrete cable tower is used in most cable-stayed bridge in our country.The stress of pylon anchorage zone is complex,which is the key of design.Isolated inclined tower and cabled-stayed structure of asymmetry is used in some bridge.Finite element method is carried on for analyzing the stress of anchor zone in prestressed concrete cable-stayed tower in the paper.The arrangement of prestressed tendons is decided by the stress and analysis result. |
