Reliability of structures in high dimensions, part I: algorithms and applications

PS Koutsourelakis, HJ Pradlwarter… - Probabilistic Engineering …, 2004 - Elsevier
The present paper is concerned with the estimation of structural reliability when a large number
of random variables is present. A sampling technique which uses lines in order to probe …

Application of line sampling simulation method to reliability benchmark problems

HJ Pradlwarter, GI Schueller, PS Koutsourelakis… - Structural safety, 2007 - Elsevier
A procedure denoted as Line Sampling (LS) has been developed for estimating the reliability
