In this study, measured data of cable-supported bridge’s thermal expansion and contraction were analyzed. To evaluate structural behaviors by temperature variations, measured data were compared with theoretical values by correlation analysis between thermal movements and temperatures. Additionally, the cumulative displacements were analyzed. Through the analysis of the results, the evaluation methods of cable-supported bridge's thermal expansion and contraction is suggested.
