Behaviour Verification of Gas Transfer Buried Steel Pipelines by Propagation of Seismic Waves in Soil Types

The most important parameter for determining the level of performance and breakdown of buried pipes in the case of earthquake is the maximum value of strain. Vital arteries code, while studying the maximum value of strain, have addressed the seismic behavior of buried pipelines. Static methods don’t...
