Modal Analysis Theories and Methods for Bridge

Abstract:

Article Preview

According to the dynamic theory and characteristics of the bridge modal analysis theories and methods for bridge were introduced which mainly included solving the nature frequency, mode shape, and damping ratio with the Rayleigh-Ritz method, subspace iteration method. And the application of bridge modal shape sequences and frequencies with their changes were illustrated in the diagnosis of the bridge disaster. Dynamic testing of the bridge should be measured for vibration mode and frequency which could be used to analyze the change of supports, constraints and other facilities of the bridge and to predict the working condition of the structure.
