Abstract

Recent earthquakes have damaged many lifeline structures. Buried gas pipelines are also no exceptions. Sometimes, theses pipes are subjected to a thinning of the wall thickness due to corrosion. Therefore, it is important to evaluate the strength of the pipes undergoing local wall thinning to maintain the integrity of the piping systems. The main purpose of this study is to understand failure aspects of buried pipeline caused by earthquake and degradation of metal due to corrosion through FEM. In dynamic analysis, corroded pipeline approaches to critical criteria (reaching the yield stress) in much less time. In this case, if the corroded pipe thickness be half, the yielding angle is reduced to a quarter.
