Finite Element Model Updating Methods for Structural Application [PDF]
Common Foundations 2021, 2021 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.

Finite element model updating for structural applications [PDF]
Journal of Computational and Applied Mathematics, 2020 A novel method for performing model updating on finite element models is presented. The approach is particularly tailored to modal analyses of buildings, by which the lowest frequencies, obtained by using sensors and system identification approaches, need to be matched to the numerical ones predicted by the model.
