In Japan, after 'the Great Hanshin Earthquake' disaster, passive vibration control technologies are becoming more necessary for either industrial or non-industrial facilities and structures. Reduction in the responses will be significantly obtained by adopting seismic isolation systems or by installing passive energy absorption systems into the structural members of equipment, facilities or buildings in which the seismic safety against the large inputs is strongly required not only for the improvement of the seismic reliability of the structure but also for maintaining the operational functions during or after earthquakes. However, by this time, any applications of seismic isolation systems to industrial facilities such as thermal power stations and high pressure gas facilities, although the over 800 earthquake isolated buildings have been already constructed in Japan. Few examples of installing energy absorbers into industrial structures also can be found while many applications in buildings can easily be found. This paper outlines the present state of applications and R&D of passive energy dissipation systems and seismic isolation systems to industrial structures in Japan.
