Research on Construction Techniques for System Transformation of Self-Anchored Suspension and Cable-Stayed Combination System Bridge

The self-anchored suspension and cable-stayed combination system bridge is a new type of bridge which is aesthetic in appearance and skillful for the design. In order to analyze the mechanical behavior of the bridge on the process of system transformation, the model of spatial member finite elements was established. In addition the model test with the similarity ratio of 1:20 was carried out. Through comparing with the results of the theoretical analysis and the experimental results, the deformation regularities of main cables and the change of suspender force on self-anchored suspension and cable-stayed combination bridge were got. The results also indicates that this paperpsilas method is correct. The research results provide the basis for design and construction of this type of bridge.
