Methodology for Evaluating Dredged Material Alternatives Using Risk-Cost Analysis Under Uncertainty
A methodology and a case example was presented at the 1989 Conference on Risk-Based Decision Making in Water Resources, Santa Barbara, to perform risk-cost analysis for dredged material...
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....
Implementing Uncertainty Treatment in AI Development Environment
The seismic vulnerability of existing masonry buildings is investigated by an expert system prototype. Field inspectors have to provide answers which can be of a Boolean, fuzzy or probabilistic...
Reliability-Based Specification for Engineered Wood Construction
A three-year, industry-sponsored effort has resulted in the development of a reliability-based, load and resistance factor design (LRFD) Specification for wood construction. Improvements...
International Harmonization of Reliability-Based Timber Engineering Design Codes
An overview is presented on reliability-based timber design code activities in various major timber producing and consuming countries. The overview is based on information generated through...
Probability Model of Load Exceedances under Cyclic Loadings
A probability model for nonlinear load exceedances subjected to a Poisson process with reversible cyclic load pulses was developed and is presented in this paper. A reversible cyclic load...
Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...
Comparison of Wind Cross-Spectral Data with Models
Existing analysis procedures for the prediction of long-span bridge response to wind have until recently neglected the horizontal-vertical cross-spectral components of the wind under the...
Inspection Planning for Surface Fatigue Cracks
A reliability based method for planning of inspections to detect surface fatigue cracks is presented. Cracks are described as semi-elliptical surface cracks. The conditions governing fatigue...
Some Remarks on BK-Models for Fatigue Crack Growth
The choice of a model parameter for concentrating the entire uncertainties of a constant load amplitude fatigue crack growth process is shown to be sufficient when reproducing the first...
A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
A Stochastic Approach to the Fatigue Reliability
In this paper, the stochastic approach, which combines the mixed boundary integral equation method (Lua et al (1992a)) with the First Order Reliability Method (FORM), is applied to study...
Some Modeling and Analysis Techniques for Wave Propagation in Random Media
Some mathematical modeling techniques for the problem of wave propagation in randomly imperfect periodic medium are reviewed: multiscale formulation and random evolution modeling. These...
Wavefront Propagation in Random Granular Media
A very brief account is given of a stochastic method developed for analysis of transient waves propagating in one-dimensional random granular-type media. The method is suited to study...
Fatigue Strength of Welded Joints Under Broadband Loadings
Twelve welded high strength steel cruciform specimens were tested under stochastic loadings to determine the influence on fatigue life of the bandwidth of the loading process. Constant...
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...
Fatigue/Fracture Reliability and Maintainability of Structural Systems: A Method of Analysis
Fatigue and fracture of structural components are the principal modes of failure for those structural systems that are dominated by tensile dynamic (oscillatory) loads. As the structure...
TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
