| Abstract: | In order to promote the development of CFRP cable-stayed bridges in China,a study is carried out on the design and application of the first cable-stayed bridge with CFRP cables in China.In the study,the design essentials of the main components of the bridge are elaborated and their integral performances are analyzed by using the finite element method.Combined with the construction of the bridge,the performances of various types of adhesive anchorages are analyzed,a new type of adhesive anchorage is developed,and five sets of experimental CFRP cables are tested.The manufacture and installation techniques of CFRP cables are elaborated.Based on the results of construction simulation,a scheme to apply the full tension in one single operation is proposed,and the measurement data during tensioning of the cables are analyzed. |
