Lifetime Reliability of Wood Structural Systems
A model to predict ultimate capacity reliability of wood systems is developed. The model is analogous to Markov cumulative damage models. System ultimate capacity is defined as failure...
Reliability of Multistate Structural Systems
The theory of system reliability consists of establishing the relationship between the reliability of a complex system and the reliability of its components. Often, the system and its...
Failure Probability Estimation of Series Systems
In this paper, an approximation scheme is presented for analysis of series structural systems where no exact solution exists. If the safety indices of the individual failure functions...
System Reliability Using Expert Opinion
The objective of the study on which this paper is based was to determine the safe performance of several different interior gas piping systems. This paper describes the piping systems...
An Expert System for Reliability Engineering
The goal in this project is to create an expert system to do failure mode investigations from 'first principles,' or the basic understanding of the way components...
Structure of the Expert FRAMEX System on Fracture Mechanics
The FRAMEX expert system gathers, through independent modules, knowledge analysis techniques to be used by an expert for developing a fracture problem diagnosis. The system includes three...
Experiences with Applications of Importance Sampling in Structural Reliability Computations
This paper presents some experiences and observations relating to the use of importance sampling in structural systems reliability computations. These are presented with three examples,...
Reliability Based Optimal Structural and Mechanical Design
A reliability based optimal design strategy has been developed. Nonlinear limit state functions and nonnormal random variables can be accommodated. For structural systems analysis, a failure...
A Kinematic Approach to Simulation-Based System Reliability Evaluation
System reliability of complex structural engineering systems is often estimated by simulation-based procedures, with failure analysis based on a static (limit state) formulation or a kinematic...
Reliability Methods for Steel Members Subjected to Axial Load and Moment
There has been a significant amount of research performed on determining the reliability of elastic-plastic frames where failure is through the formation of a plastic collapse mechanism....
Effects of Nonlinearities on Structural Reliability and Serviceability
Serviceability and failure limit states are computed using the Simple Plastic Theory (SPT) as well as with a Nonlinear Structural Analysis Program (NSAP). Geometric and material nonlinearities...
Reliability of Large Structural Systems Under Time Varying Loads
Time invariant reliability analyses of structural systems are generally carried out by using the well-known failure mode approach. To include the time varying effects of loads, concepts...
Reliability of Daniels-Systems Oscillators Including Dynamic Redistribution
The reliability of redundant systems under stationary Gaussian white noise excitation is investigated with emphasis on the dynamics of redistribution of internal forces after brittle failure...
Efficient Methods in Time Dependent Reliability
A general and efficient method is presented for computing failure probabilities for components and systems where the uncertainties are represented by a mixture of random variables and...
Engineering Reliability: The Organizational Link
Organizational factors may significantly affect systems' reliability, but they are not typically included in modeling. This paper discusses how the stochastic models of system...
Probability of Failure Under a Biaxial State of Stress
Structural components are subjected to uniaxial stress states only infrequently. Even under such simple conditions as direction tension or bending the presence of holes, cutouts and other...
Time Variant Reliability Analysis Using Bivariate Diffusive Crack Growth Models
This paper is concerned with the development of a time-dependent reliability concept. The time variant load carrying capacity, i.e., resistance, of a structure caused by fatigue is expressed...
U.S. Embassy In Moscow: A Structural Stalemate
The fate of the nearly finished American embassy in Moscow should be decided by next fall. In the meantime, it stands empty. On April 15, 1987, Congress made public a National Bureau of...
Inspection of Under Bridge Length Culverts
Culverts over 20 feet in span length are classified as bridges and are inspected under the National Bridge Inventory and Inspection Program. Those facilities under bridge length, less...
Water Main Condition Monitoring A Case Study
Water main breaks, routine occurrences for water utilities, reflect the structural failure of the main. The trend in break patterns is increasing for many utilities in the U. S. Several...
