Abstract

This paper presents the results of a static testing program designed to determine the axial stiffness and strength characteristics of some typical restrained pipe joints. Pipelines have suffered damage and failure from past earthquakes and are vulnerable to seismic motions. A vast majority of the pipeline failures have occurred at unrestrained pipe joints due to pull-out, and therefore, the effectiveness of restrained pipe joints needs to be examined and their response to earthquake motion needs to be assessed in order to help mitigate potential damage. This paper also suggests methods to use test results for pipeline network analysis and for risk assessment procedures.
