The Random Finite Element Method (RFEM) in Settlement Analyses

, 2007
In order to control serviceability problems arising from excessive settlement of shallow footings, geotechnical design codes generally include specifications regarding maximum settlement which often govern the footing design. Once the footing has been designed and constructed, the actual settlement it experiences on a real three-dimensional soil mass ...

Random Set Finite Element Method Application to Tunnelling

Proceedings of the 4th International Workshop on Reliable Engineering Computing Robust Design – Coping with Hazards, Risk and Uncertainty – REC 2010, 2010
A real tunnel project is used to demonstrate the validity of Random Set Finite Element Method (RS-FEM) framework in geomechanics where engineers have to face not only imprecise data but also lack of information at the beginning of the project. The objective of this paper is to illustrate the RS-FEM approach, which in the authors' view is an appealing ...

A practical approach for reliability analysis of unsaturated slope by conditional random finite element method

Computers and geotechnics, 2018
The paper presents a method for reliability analysis of slopes in unsaturated soils. Conditional random fields are simulated by consideration possible fluctuations of the measured soil properties.

Analysis of the Stability of Thawing Slopes by Random Finite Element Method

Transportation Research Record, 2019
A significant number of landslides occur in cold regions because of freezing and thawing cycles. The instability of thawing slopes can cause serious damage to transportation infrastructure and property, and even loss of human life. This type of landslide

Finite element/difference methods in random vibration

Computers & Structures, 1986
Summary: Finite element and finite difference analyses of a class of random vibration problem are presented. The random field equations are discretized using the standard finite element/difference techniques. Recursive algorithms for the moments of the response in terms of the moments of the random loading and random initial condition are derived based

A Finite Element Method for Random Differential Equations with Random Coefficients

SIAM Journal on Numerical Analysis, 1979
A finite element method is derived for solving equations of the following type \[ - (p(x)u'(x,\omega ))' + (q(x) + r(x)\lambda (\omega ))^2 u(x,\omega ) = f(x,\omega ),\quad 0 \leqq x \leqq l,\] with boundary conditions $u(0,\omega ) \equiv u(l,\omega ) \equiv 0$ where (i) $0 < p \in C^1 [0,l]$; (ii) $q,r \in C[0,l]$; (iii) $f(x,\omega ) = B'(x,\omega )

Probabilistic Settlement Analysis by Stochastic and Random Finite-Element Methods

Journal of Geotechnical and Geoenvironmental Engineering, 2009
The paper discusses finite element models for predicting the elastic settlement of a strip footing on a variable soil. The paper then goes on to compare results obtained in a probabilistic settlement analysis using a stochastic finite element method based on first order second moment approximations, with the random finite element method based on ...

A consistent finite element method for random response problems

Computers & Structures, 1972
Abstract A consistent finite element method for analysing the random response of complex structures is developed. The method is based on the standard modal approach but using the mode shapes obtained from a finite element representation of the structure.
