A Statistical Method for the Reliability of Mechanical Components
The usual statistical treatment of data for the reliability of components is to fit a distribution to them and then to use this theoretical distribution for predictions. But since this...
Experimental Validation of a Probabilistic Fracture Mechanics Model
A method is developed for validating a probabilistic fracture analysis code (PROFRANC). The method is based on classical statistical techniques and experimental data. It is shown that...
Fabric Related Probabilistic Model for Granular Materials
A new anisotropic noncoaxial incremental constitutive model for granular materials (Jahedi et al., 1990) was developed, in which a Fabric reconstruction factor '?+',...
Risk Based Optimal Fatigue Testing
Optimal fatigue life testing of materials is considered. Based on minimization of the total expected costs of a mechanical component a strategy is suggested to determine the optimal stress...
Time-Variant System Reliability Analysis Using Response Surface Methodology and Fast Integration
An approximate method is presented to solve the structural reliability problem of complex structural systems subjected to time-variant loads where the parameters of the structural system...
Critical Buckling Load Statistics of an Uncertain Column
The objective of this paper is to examine the statistics of the buckling load of a column with uncertain material properties. The elastic modulus is assumed to be a random process that...
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....
Retention Parameter Estimates for Curve Number Runoff Procedure
A technique is developed for computing estimates and associated probabilities of the retention parameter S in the Soil Conservation Service curve number runoff procedure. This technique...
Stochastic Simulation and Optimization of Irrigation Canal Network Flows
This paper investigates the effects of parametric and objective uncertainty on simulation and optimal hydraulic design of irrigation canal networks. A model of spatially-varied flow in...
Risky Business: Can We Believe Port Risk Assessments?
What is the risk that a maritime incident resulting in catastrophic consequences (environmental damage or loss of life) could occur in a U.S. port or waterway? How does one calculate the...
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....
Decision Analysis Model for Well Rehabilitation and Groundwater Development, Moses Lake, Washington
A decision analysis model has been developed for evaluating various well rehabilitation strategies and long-term groundwater development alternatives, as well as various investigation...
Statistical Analysis of Wastewater Flow Reduction
Changes in urban water use patterns can significantly impact wastewater flow characteristics. With the increased emphasis on water conservation programs, understanding these impacts is...
The Diagnosis of Pavement Ills
The paper defines the 'health' of a road pavement in terms of parameters of serviceability, safety and structural integrity and defines 'illness' as any departure from 'healthy' values...
Transportation Planning and Air Quality
This proceedings,
Specifying the Offshore Environment
Hindcasting has become a generally accepted method of producing long time series of environmental events from which environmental design criteria can be developed. The need for reliable...
Validation of the SEADYN90 Cable Simulation Model Using a Three-Dimensional Cable Deployment Data Set
This paper presents data from a full-scale, three-dimensional cable payout test and the corresponding numerical simulations using the SEADYN90 computer model. The experiment, which was...
Spectral and Statistical Characteristics of Wind Waves Off Canary Islands
Wave climate around Canary Islands is studied by means of statistical and spectral techniques. Maximum Entropy Method is used for obtaining the spectral density function. Autocorrelation...
Equivalent Statistical Quadratization of Nonlinear Hydrodynamic Loads on TLPs
In this paper, a new method is proposed for the expansion of nonlinear drag forces expressed in terms of multivariate Hermite polynomials correct up to the second-order. The drag force...
