Finite element model updating methods for structural application

Structural finite element models are a modern tool for continuous monitoring of structures, damage detection, prediction of service life and determination of optimal strategy for maintenance. It is well known that we get uncertain numerical models due to the input parameters such as stiffness, mass, and boundary conditions. To solve this problem, finite element model updating methods are used in combination with the results of structural dynamic tests or structural health monitoring data. In this paper, a brief overview of the procedure for updating finite element models using experimentally determined structural dynamic parameters - natural frequencies and natural modes - is given. Some of the most commonly used methods are listed and their advantages and disadvantages are highlighted.
