Hanzlik, Petr, Auteur ; Diniz, Sofia, Auteur ; Grazini, Andrea ; Mircea Grigoriu ; Emil Simiu |The Methodology for estimating wind effects presented in this paper is based on the database-assisted design approach. It accounts for the effects of wind directionality, for the uncertainties in the parameters that determine wind effects, nd fo[...]

Mircea Grigoriu, Auteur ; Schueller, Gerhart L., Éditeur scientifique |The Karhunen-Loève, spectral, and sampling representations, referred to as the KL, SP, and SA representations, are defined and some features/limitations of KL-, SP-, and SA-based approximations commonly used in applications are stated. Three tes[...]

Mircea Grigoriu, Auteur ; Arvid Naess, Éditeur scientifique |Algebraic equations with random coefficients, referred to as stochastic algebraic equations, are used extensively to solve approximately differential equations describing mechanics problems with uncertain material properties and applied loads. T[...]

R. V. Field, Auteur ; Mircea Grigoriu, Auteur |Mathematical models are developed and used to study the properties of complex systems in just about every area of applied science and engineering. Information on the system being modeled is, in general, incomplete, so that there may be two or mo[...]

A real-valued random field {Zi,j} with piecewise constant samples and defined on a lattice L in [openface R]2 is developed to characterize two-dimensional metallic polycrystals. The subsets defined by constant values of {Zi,j} are virtual grains[...]

Sanjay R. Arwade, Auteur ; Schueller, Gerhart L., Éditeur scientifique ; Mircea Grigoriu, Auteur |A two part probabilistic model for polycrystalline microstructures is described. The model utilizes a Poisson.Voronoi tessellation for the grain geometry and a vector random field model for the crystallographic orientation. The grain geometry mo[...]

Cagdas Kafali, Auteur ; Mircea Grigoriu, Auteur |Seismic fragility of a structural, nonstructural and/or geotechnical system is the probability that a system response exceeds a critical value under seismic ground motions of specified intensities. Fragility curves are plots of system fragilitie[...]

Mircea Grigoriu, Auteur ; George Deodatis, Auteur |A new model is developed for non-Gaussian processes. The model is based on the spectral representation theorem for weakly stationary processes, can match the second moment properties and several higher order moments of any non-Gaussian process, [...]
