Vehicle-bridge dynamic interaction using finite element modelling [PDF]
, 2010 First investigations on the dynamic response of bridges due to moving loads were motivated by the collapse of the Chester railway bridge in the UK in the middle of the 19th century.

Structural model updating and prediction variability using Pareto optimal models [PDF]
, 2008 A multi-objective identification method for structural model updating based on modal residuals is presented. The method results in multiple Pareto optimal structural models that are consistent with the experimentally measured modal data and the modal ...

Finite element model updating for damage detection [PDF]
PAMM, 2005 AbstractIn this contribution we derive the iterative finite element model updating algorithm. The ability of the method to detect the damage is verified by means of a simulation with a reference finite element model. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Updating of Finite Element Models Including Damping [PDF]
Transactions of the Korean Society for Noise and Vibration Engineering, 2012 Finite element models are updated in two stages in this paper. In the first stage, damping is neglected, and mass and stiffness matrices of a finite element model are updated using an optimization technique. The objective function for optimization consists of natural frequencies and mode shapes obtained from experimental modal testing data and finite ...

Finite element model updating of natural fibre reinforced composite structure in structural dynamics
MATEC Web of Conferences, 2016 Model updating is a process of making adjustment of certain parameters of finite element model in order to reduce discrepancy between analytical predictions of finite element (FE) and experimental results.

A Statistical Model Updating Method of Beam Structures with Random Parameters under Static Load
Applied Sciences, 2017 This paper presents a new statistical model updating method of beam structures with random parameters under static load. The new updating method considers structural parameters and measurement errors to be random.

Experimental Studies on Finite Element Model Updating for a Heated Beam-Like Structure
Shock and Vibration, 2015 An experimental study was made for the identification procedure of time-varying modal parameters and the finite element model updating technique of a beam-like thermal structure in both steady and unsteady high temperature environments.
