“…17. The numerical estimation of the VRF through fast MCS is very important as the closedform analytic expressions existing in the literature involve modulating functions that are very difficult to establish even in the simplest cases of statically indeterminate linear beams [8] or statically determinate beams with nonlinear (power) constitutive laws [16]. The fast MCS procedure can be implemented into the framework of a deterministic FE code making this approach very general.…”

“…In these approaches, linear material properties were implemented although the variations in these are not typically critical to structural reliability analysis. Recent advances include extension of this approach to nonlinear and/or dynamic problems . Different aspects and applications of the VRF were introduced in , while an efficient fast Monte Carlo simulation for the numerical computation of VRF of this approach was provided in .…”

“…The numerical estimation of the VRF through a fast MCS procedure based on Eq. (4.59) (see below), is very important as the closed-form analytic expressions existing in the literature involve modulating functions that are very difficult to establish even in the simplest cases of statically indeterminate linear beams (Papadopoulos et al, 2006) or statically determinate beams with nonlinear (power) constitutive laws (Teferra and Deodatis, 2012), as well as for plane stress/strain systems (Arwade and Deodatis, 2011;Wall and Deodatis, 1994). In these studies, it is shown that the VRF is a function of the deterministic parameters describing the geometry, material properties and loading of the structure.…”

“…That is, VRFs provide insight into the importance of the shape of the spectral density functions of the random properties on the response variance. The proof of VRF existence in the nonlinear problems considered in this thesis is not straightforward and requires the application of a generalized VRF methodology described by Teferra and Deodatis (2012).…”
