Seismic design of high-pressure gas facilities had been carried out in accordance with MITI notification 515 “Seismic Design Code” established in 1981. The Great Hyogoken-nanbu Earthquake occurred in 1995. Some facilities and piping systems were damaged due to ground displacement (settlement and/or lateral movement) induced by liquefaction. Having learned from the experiences, the seismic design code was amended in 1997. This paper introduces requirements in the new seismic design code and the evaluation method of Required Seismic Performance proposed.
