An enhanced substructure coupling technique for dynamic re-analyses: Application to simulation-based problems
(2016)This work presents the implementation of an enhanced substructure coupling technique in the context of complex simulation-based problems. Attention is focused to problems requiring a large number of dynamic re-analyses of ... -
Information-driven modeling of structures using a Bayesian framework
(2018)This work presents a comprehensive Bayesian framework for integrating information from data and models of civil infrastructure systems. In the proposed framework, modeling uncertainties are quantified and propagated through ... -
Model reduction techniques for structural dynamic analyses
(2019)This chapter presents a model reduction technique based on substructure coupling for dynamic analysis. The dynamic behavior of the substructures is described by a set of dominant fixed-interface normal modes along with a ... -
Model-reduction techniques for reliability-based design problems of complex structural systems
(2016)This work presents a strategy for dealing with reliability-based design problems of a class of linear and nonlinear finite element models under stochastic excitation. In general, the solution of this class of problems is ... -
Reliability analysis of dynamical systems
(2019)The use of reduced-order models in the context of reliability analysis of dynamical systems under stochastic excitation is explored in this chapter. A stochastic excitation model based on a point-source model is introduced, ... -
Reliability sensitivity analysis of stochastic finite element models
(2015)This contribution presents a scheme for integrating a model reduction technique into a simulation-based method for reliability sensitivity analysis of a class of medium/large nonlinear finite element models under stochastic ...
