A COMPARISON OF BRIDGE LOAD CAPACITY USING ACCELEROMETER AND STRAIN GAUGE DATA
This paper describes a load-test procedure using accelerometer response and compares the results with that obtained using the traditionally used strain-gage data. The load rating provides an approximate load capacity of a bridge based on the available capacity of a critical girder for a predefined loading path. The results indicate that the accelerometer can conveniently extract information of bridges irrespective of their material status. Application of the accelerometer to a cracked concrete girder is quite useful for bridge load rating. Accelerometer data also provide additional information to measure the vehicle-bridge dynamic interaction.
