Firefighting water pipeline requires seismic safety performance and serviceability after an earthquake. However their periodical maintenance is difficult due to underground installation. This study proposes conventional seismic diagnous chart of the underground pipeline in order to check their seismic safety performance easily. The pipeline network is composed of deformed pipes such as bend, Tee, and several types of fitting as well as straight pipes, and their seismic performance depends on the shape of pipeline. This study analyzes the seismic behavior of pipeline network with comparison of the straight pipelines in terms of the displacements of jointed parts quantitatively. Response due to different types of pipe and other factors is considered as modification coeffifient in the chat.
