Transitional markov chain monte carlo method for bayesian model updating tapuz dating
Department of Civil and Environmental Engineering, Jackson State University, 1400 J. The vibration-based structural health monitoring has been traditionally implemented through the deterministic approach that relies on a single model to identify model parameters that represent damages. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.A new sampling method of the transitional Markov chain Monte Carlo is incorporated with the structure’s finite element model for implementing the approach to damage identification of truss structures.This method can not only draw samples which approximate the updated probability distributions of uncertain model parameters but also provide model evidence that quantify probabilities of uncertain model classes.The former could lead to model uncertainties due to the discrepancy between physical configurations and their mathematical models, while the latter could induce model parameter uncertainties due to difficulty in obtaining accurate model parameters of complex joint details.This paper is to present a new perspective for addressing uncertainties associated with truss joint configurations in damage identification based on Bayesian probabilistic model updating and model class selection.The Gibbs sampler is a special case in which the proposal distributions are conditional distributions of single components of a vector parameter.
There are certainly references to more advanced things than what I’m going to cover in this post.

When such approach is applied for truss bridges, truss joints are usually modeled as either simple hinges or rigid connections.
Yes for posting it here we would have to make it like that.
Wouldnt work for me though as my ATMCMC is not in the installed distribution in linux and therefore it wouldnt find it. file to the examples directory and make it run stand-alone and produce the nice plots?
