The Research on Impact Vibration Test Method for Bridge Piers

Abstract:

This paper conducts an analytical research on the use of bridges, and discusses how the vibration of bridges is affected by the healthiness of piers. Meanwhile, Impact Vibration Test Method is introduced, by which the modal parameter of bridges can be tested. A lot of dynamic tests of piers are conducted by using this method. By analyzing data and identifying modal information of piers, this paper made a conclusion on the general law of the impact each parameter has on characteristic frequency of the piers. The bridge finite-elemental model is constructed according to the actual structure of piers, the impact vibration test load stimulated, then computed and analyzed with the dynamic time-history method. Bases on the comparison between test result and frequency of Time-domain transverse velocity received the results of the analyses identify the frequency spectrums, the validity of the Impact Vibration Test Method is verified.
