چکیده
In this paper we study the reliability of calculations of the structural reliability. It compares the exact reliability expression within the Bernoulli-Euler column theory with its counterpart obtained via the finite difference expression in the buckling context.

Reliability estimation of Iran's power network
Today, the electricity power system is the most complicated engineering system has ever been made. The integrated power generating stations with power transmission lines has created a network, called complex power network. The reliability estimation of such complex power networks is a very challenging problem, as one cannot find any immediate solution methods in current literature. In this pape...
متن کاملModeling of Epistemic Uncertainty in Reliability Analysis of Structures Using a Robust Genetic Algorithm
In this paper the fuzzy structural reliability index was determined through modeling epistemic uncertainty arising from ambiguity in statistical parameters of random variables. The First Order Reliability Method (FORM) has been used and a robust genetic algorithm in the alpha level optimization method has been proposed for the determination of the fuzzy reliability index. The sensitivity level ...
متن کاملReliability Sensitivity Estimation of Linear Systems under Stochastic Excitation
The objective of this paper is presenting an approach for reliability sensitivity estimation of linear structural systems subject to dynamical excitation characterized as a Gaussian process. The paper represents an extension of some ideas proposed previously in the context of sensitivity analysis. Novel aspects include the use of the Bootstrap method for assessing the error associated with the ...
متن کاملCertification in Structural Health Monitoring Systems
Despite advances in health monitoring systems, the certification process for automated SHM systems remain rooted in the probability of detection (POD). POD is a fundamental part of the certification process, however, it is not the only measure of system validity. The process to certify a system must contain measures of accuracy and reliability. Disclosing the accuracy and reliability at the tim...
