Bayesian evidence for finite element model updating

, 2008
This paper considers the problem of model selection within the context of finite element model updating. Given that a number of FEM updating models, with different updating parameters, can be designed, this paper proposes using the Bayesian evidence statistic to assess the probability of each updating model.

Sensitivity analysis of damaged monumental structures: the example of S. Maria del Suffragio in L'Aquila [PDF]

, 2013
In Italy, which accounts for an impressive number of architectural heritage sites, a large part of the territory is subject to seismic risk. Nonetheless, also the two recent examples of the 2009 L'Aquila earthquake and 2012 Emilia earthquake confirmed ...

Bayesian finite element model updating based on Markov chain population competition

Jixie qiangdu
The traditional Markov chain Monte Carlo(MCMC） simulation method is inefficient and difficult to converge in high dimensional problems and complicated posterior probability density.In order to overcome these shortcomings, a Bayesian finite element model ...
