Abstract
Abstract: This work presents an algorithm that automatically identifies the equivalent mass and speed of vehicles crossing a long-span suspension bridge utilizing ambient vibrations data. The first goal is to estimate vehicle characteristics that can be further used to gather information about the level of serviceability loading of the bridge, as well as provide relevant data for smart asset management. Sensors are used to measure the vibrations and secondary inputs to the system are used to actuate the flexible body in order to obtain some desired structural response. As that, for longer span bridges the change in stiffness of the track has a negligible effect on the acceleration and displacement. All analysis have done using MATLAB tool.
