Dynamic Assessment about Simple-Supported Girder Bridge
The objective of this study is to introduce a dynamic assessment method about simple-supported girder bridge .This paper introduces the dynamic test contents, test methods, test results and the assessment index. The dynamic tests included ambient vibration tests which were used to identify the bridge modal parameters and forced vibration tests based on controlled traffic loads which were used to obtain the and vibratory response. The analytical results showed that the dynamic performance was in good condition and the bridge had great potential of carrying capacity. This method provided effective means for the assessment of the existing simplesupported girder bridge.
