The Role of Decision Rules on Structural Safety Evaluation Systems
Three steps are involved during an assessment procedure. The first step is to make a diagnosis for possible causes of the damage, the second is to perform a qualitative evaluation including...
Importance Sampling in Structural System Reliability
In structural system reliability analysis, it is frequently necessary to resort to Monte Carlo simulation (MCS). This paper focuses on Importance Sampling, an advanced MCS method, which...
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,...
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...
System Reliability Under Time Varying Load
The reliability of ductile and brittle structural systems under time varying loads is investigated. The formulation in the context of outcrossing of a vector process is examined. A new...
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...
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...
Stochastic Finite Element Analysis of Railroad Tracks
The loads acting on railroad tracks due to the passage of trains and the resisting track parameters have a random character. The purpose of this study is to incorporate the random parameters...
Reliability Analysis in the Presence of Random Functions and Categorical Variables
This paper describes a reliability procedure that can handle certain classes of random functions and qualitative categorical variables. The method is an extension of the R. Rackwitz-B....
