Finite Element Model Updating of Scale Bridge Model Using Measured Modal Response Data
One of the most promising fields of finite element model updating involves using data obtained from the modal response of a structure to update a finite element model. The University of Central Florida (UCF) has constructed a scale model of a two span bridge. Using an impact hammer and accelerometers mounted on the structure, the first 17 natural frequencies and mode shapes were identified. Using two different residual error functions, a subset of the measured modal data was used to verify and update a finite element model of the structure so that it better reflects the behavior of the system. The results of the updating process are presented.
