Efficient Reliability Sensitivity Estimation Applying Line Sampling

摘要

This paper presents a Line Sampling framework for estimating reliability-based sensitivity measures with respect to the parameters of the random input quantities.The proposed framework requires minor additional numerical cost to that already involved with Line sampling conventional analysis and can be carried out as a post-processing step.The proposed framework is developed with two different strategies.A numerical example involving a foundation laid over an elastic soil layer has been used to illustrate the framework and its computational efficiency
