Abstract

The semi-empirical and semi-theoretical method is adopted to simulate the response of gas continuous buried pipelines subjected to seismic wave propagation. Using the peak ground velocity (PGV) as the intensity measure, the maximum axial responses (strain or stress) of pipelines are calculated. The seismic safety factor is employed as earthquake damage index of a pipeline and the relation between earthquake damage index and earthquake damage level is presented to determine the earthquake damage level with respect to seismic intensity. The weighted statistical average method is introduced to estimate the earthquake damage indexes and earthquake damage states of pipeline network under different seismic intensities. According to the results of numerical example, it is concluded that the improved method is effective and practical.
