Abstract:

The Structural Health Monitoring System on the bridges continue to develop to ensure that the bridge being monitored is in good condition to serve traffic. One of the main bridge’s parameter observed is deflection of the bridge. Various methods has been developed to be able to monitor deflection accurately and economically. This study presents a method of determining the maximum deflection of a three-span continuous bridge using rotation data obtained from a tilt meter with linear regression. Initial data were obtained from FEM simulations under various load conditions to obtain the maximum deflection value and the rotations. Furthermore, linear regression was carried out to obtain the relationship between the four rotational data and the maximum deflection. The accuracy of the maximum deflection value is then compared with the results of the analysis using FEM. The accuracy rate obtained in this study is about 93.6%.
