An engineering survey of the first cable-stayed bridge usingCFRP cables was firstly introduced ; then a three-dimensional computational finite element dynamic model based on beam elements,shell elements and bar elements of above CFRP cable stayedbridge was modeled and a structure dynamic property analysis was put up; lastly a dynamic property test under ambient excitation was put up to analyze the dynamic characteristics of the first cable-stayed bridge using CFRP cables in China, at the same time, a contrast analysis between test results and calculational results of finite element method was presented. The analysis result shows the low order vibratory frequency and mode are basically tallied between test results and calculational results of finite element method. The test and analysis results of this paper could provide reference for dynamic modeling and characteristic analyzing ,seismic and wind loads resistance designing of CFRP cable-stayed bridge,also it could provide reference for the further engineering application of CFRP material used as cables on bridge structure by all means.
