Seismic Performance of Complicated Pipeline Network
Abstract eng: Since the pipeline network is composed of deformed pipes such as bend, Tee, and several fitting as well as straight pipes, its seismic performance is complicated. The concentrated stress due to the seismic load generally acts on the deformed pipes so that the relative displacement between soil and pipe occurs. From the practical sense, the earthquake response analysis of straight pipeline is not enough to explain the seismic performance of whole pipeline network. This study developed a new numerical analysis method, which can simulate the seismic behavior of complicated pipeline network with several branches. Moreover, seismic performance of the pipelines network jointed by bend and Tee pipes is analyzed with comparison of the straight pipelines in terms of the displacements of jointed parts quantitatively. Finally the evaluation method to assess the seismic performance of the complicated pipeline network is discussed throughout the analysis.
