Model Updating Techniques for Structures Under Seismic Excitation
Abstract Vibration-based system identification of structures has become a well-established way of condition assessment with the main steps of modal analyses and tracking any change in the identified modal parameters. In addition, Finite Element Model (FEM) updating is crucial especially for damage detection and reliability estimation under seismic excitation. In literature, it was shown that seismic reliability of structures with and without FEM updating turned out to be different. The main idea behind FEM updating is minimizing the difference between modal parameters obtained from FEM and system identification by changing values of parameters such as Young’s modulus of materials and soils springs constants. Real-world examples of FEM updating cover bridges, tall buildings and historical structures.
