Abstract :
The test of suspender tensioning force of suspender arch bridges is the key technology during construction stage and service stage of this bridge type. Calculation of suspender tensioning force based on measured natural frequency is the most beneficial and convenient method at present. Starting with basic principle of suspender vibration, influencing factors during the testing process of suspender tensioning force are analyzed in this paper. And based on existing research results, a test method of suspender tensioning force with high precision basis on vibration test is formed. Finally, relying on a suspender arch bridge, the formed method is verified.
