Computational Framework for Online Estimation of Fatigue Damage using Vibration Measurements from a Limited Number of Sensors
(2017)This study proposes a computational framework for the online estimation of fatigue damage using operational vibration measurements from a limited number of sensors. To infer the stress response time histories required for ... -
Dynamic response estimation and fatigue prediction in a linear substructure of a complex mechanical assembly
(2016)In this work, a computational framework is proposed for online estimation of fatigue damage, in a linear steel substructure of the entire body of a lignite grinder assembly at a PPC power plant. The proposed method is based ... -
Hierarchical Bayesian calibration and response prediction of a 10-story building model
(2019)This paper presents Hierarchical Bayesian model updating of a 10-story building model based on the identified modal parameters. The identified modal parameters are numerically simulated using a frame model (exact model) ... -
Influence of the prediction error correlation model on Bayesian FE model updating results
(2012)Bayesian finite element (FE) model updating is a probabilistic method for uncertainty quantification in FE model updating, where the well-known Bayes' theorem is used to update probability density functions of model ... -
Probabilistic damage identification of a designed 9-story building using modal data in the presence of modeling errors
(2017)Validity and accuracy of model based identification techniques such as linear finite element (FE) model updating are sensitive to modeling errors. Models used for the design and performance assessment of civil structures ... -
Vibration-based Damage Localization and Quantification Framework of Large-Scale Truss Structures
(2022)The use of structural health monitoring (SHM) systems on a regular basis is critical to achieve early damage detection, avoid unpredicted failures, and perform cost-effective maintenance planning. The main objective of ...
