A Review and Probabilistic Analysis of Limit State Functions of Corroded Pipelines

This paper introduces a new approach in developing a limit state function used in a probabilistic method when analyzing an aging structure. The so called dimensionless limit state function was formulated from the application of the well known Buckingham π theorem coupled with the multivariate stati...
