Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....
Optimal Discretization of Random Fields for SFEM
A new method for discretization of random fields (representation in terms of random variables) is introduced based on the principle of optimal linear estimation theory. The method is more...
Stochastic Finite & Boundary Element Simulations
Stochastic constitutive properties are important in real-world design-analyses. Therein the spatially varying random coefficients in field equations necessitate rather unconventional computational...

The stationary response of a linear system to random excitation is considered. A previously developed approach is extended to be applicable for the determination of both even and odd order...
Evaluation of Seismic Soil Response Using Stochastic Linearization
This paper discusses the use of stochastic linearization to non-degrading soils. First, the Bouc-Wen model parameters are reviewed. Monte Carlo simulation results are compared with the...
Stochastic Critical Excitations
Conventional methods of seismic analysis of structures frequently use the response spectrum or time history analysis techniques. The excitations for the time history analysis can be either...
Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...
Probabilistic Rotordynamics Analysis Using an Adaptive Importance Sampling Method
A methodology is developed to compute the probability of instability of a rotor system that can be represented by a system of second-order ordindary linear differential equations. The...
An Exact Expression for the Distribution of Linear Combinations of Uniform Random Variables
Structural dynamic analysis have often in the past relied on the assumption that the system under consideration is well known ahd have been associated the unpredictability of the response...
Pre-Test Selection of Static Force and Displacement Measurement Locations for Damage Assessment
An incomplete set of static force and displacement measurements are used for parameter identification of linear elastic structures at the element level. Measurement locations and the level...
Parameter Estimation in Complex Linear Structures
We present a new parameter estimation method which simultaneously computes element constitutive parameters and unmeasured displacements of finite element models from measured static responses....
Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....
