Entropy-based optimal sensor location for structural model updating
(2000)A statistical methodology is presented for optimally locating the sensors in a structure for the purpose of extracting from the measured data the most information about the parameters of the model used to represent structural ... -
Hierarchical Bayesian model updating for structural identification
(2015)A new probabilistic finite element (FE) model updating technique based on Hierarchical Bayesian modeling is proposed for identification of civil structural systems under changing ambient/environmental conditions. The ... -
Model-reduction techniques for Bayesian finite element model updating using dynamic response data
(2014)This work presents a strategy for integrating a class of model reduction techniques into a finite element model updating formulation. In particular a Bayesian model updating approach based on a stochastic simulation method ... -
On prediction error correlation in Bayesian model updating
(2013)In Bayesian model updating, probability density functions of model parameters are updated accounting both for the information contained in the data and for uncertainties present in the measurements and model predictions, ... -
Pi 4U: A high performance computing framework for Bayesian uncertainty quantification of complex models
(2015)We present Pi 4U,(1) an extensible framework, for non-intrusive Bayesian Uncertainty Quantification and Propagation (UQ+P) of complex and computationally demanding physical models, that can exploit massively parallel ... -
Updating robust reliability using structural test data
(2001)The concept of robust reliability is defined to take into account uncertainties from structural modeling in addition to the uncertain excitation that a structure will experience during its lifetime. A Bayesian probabilistic ... -
The use of updated robust reliability measures in stochastic dynamical systems
(2013)This work explores the effect of using updated robust reliability measures in the context of stochastic structural dynamical systems. A Bayesian probabilistic methodology for model updating is first implemented for the ... -
Variability of updated finite element models and their predictions consistent with vibration measurements
(2012)A case study on a small-scale laboratory vehicle frame is used to investigate the variability of the updated finite element (FE) models that arises from model and measurement errors and demonstrate the effect of this ...
