Finite element modelling and updating of a lively footbridge : the complete process [PDF]

Journal of Sound and Vibration, 2007
The finite element (FE) model updating technology was originally developed in the aerospace and mechanical engineering disciplines to automatically update numerical models of structures to match their experimentally measured counterparts.

Updating the finite element model of a Colombian Bridge with Ansys

Dyna, 2020
Updating structural model is a knowledge field that have been studied in the last decades to guarantee the reliability on the model defined to represent the behavior of a structure, but generally implies the use of different software to carry out the ...

Bayesian finite element model updating

, 2019
In this chapter, the implementation of the reduced-order models within Bayesian finite element model updating is explored. The Bayesian framework for model parameter estimation, model selection, and robust predictions of output quantities of interest is ...

Finite-element model updating of tall buildings with a computer-aided model updating system (CAMUS) [PDF]

, 2005
Dynamic behavior is one of the most important design considerations for high-rise structures; natural frequencies and corresponding mode shapes are basic data for seismic and wind response analyses.

A Paradigm Shift to Assembly-like Finite Element Model Updating. [PDF]

Aerotec Missili Spaz
In general, there is a mismatch between a finite element model {(FEM)} of a structure and its real behaviour. In aeronautics, this mismatch must be small because {FEM}s are a fundamental part of the development of an aircraft and of increasing importance with the trend to more flexible wings in modern designs.

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.

Finite Element Model Updating Combined with Multi-Response Optimization for Hyper-Elastic Materials Characterization. [PDF]

Materials (Basel), 2019
The experimental stress-strain curves from the standardized tests of Tensile, Plane Stress, Compression, Volumetric Compression, and Shear, are normally used to obtain the invariant λi and constants of material Ci that will define the behavior ...
