Research on the Method of Simply Supported Beam Modal Parameters Recognition by QY Iinclinometer

Zhai Heng, Qu Shu-Ying and Wang Guo-Liang

Abstract:
Modal parameters are of great significance in bridge structural health detection and damage identification. Nowadays structure, modal tests are mostly concentrated on acceleration response or velocity response and other responses are less to be researched. Simply supported beam is a representative structure and the research on it will help the study of other complex structures. The inclination angle data of the beam under environment excitation will be used for modal analysis in this article. The modal parameters of the simply supported beam can be got through the theoretical analysis and experimental methods separately and we find that the two results are roughly same. Therefore, by the inclination angle data of the simply supported beam we can detect modal parameters, so this article provides a new reference method for other structure modal parameters tests, expands the application range of inclinometer in engineering and provides a more reliable basis for the health monitoring and modal parameters identification of the complex bridge structures.
