Research on Dynamic Characteristics for Large Span Cable-stayed Suspension Bridges with CFRP Cables

摘要：

　　Cable-stayed suspension bridge with Carbon Fibre Reinforced Plastics(CFRP) cables is a new type of bridge structure.To study the dynamic characteristics for this kind of bridges,and its differences from cable-stayed bridges of the same span level,finite element dynamic modle of a Cable-stayed suspension bridge with main span of 1488 meters is established and a series of calculations is done.The results show that,natural frequencies of cable-stayed suspension bridges with CFRP cables are relatively small,integral frequencies are stepped and discontinuous; Its modes are centralized and the natural vibration modes show a lot of coupling; The natural frequencies of this kind of bridges are smaller than cable-stayed bridges of the same span level,the entire stiffness decreased.
