Recent Earthquakes

The 1995 Kobe earthquake extensively damaged bridges and triggered research and review as a consequence of recent earthquakes that have led to significant advances in bridge seismic design. This paper presents how this has affected design philosophy and design codes in Japan compared to seismic design codes in EC, New Zealand, and the United States concerning design philosophy, near-field ground motions, design force and ductility requirements, linear/nonlinear static/dynamic response analysis, and treatment of liquefaction and liquefaction-induced lateral ground movement.

Dr. Heki Shibata, Professor Emeritus of the University of Tokyo, who authored this paper, is a pioneer in earthquake engineering in Japan and the leading expert in mechanical engineering and seismic design of involving pressure vessels and piping equipment of nuclear power plants and high-pressure gas plants. In this paper, he classifies and analyzes mode failures and failure mechanisms in a variety of equipment based on his experience in surveying the damage to industrial facilities caused by the 1964 Niigata Earthquake and the 1971 San Fernando Earthquake. He proposes introducing the "factor of importance" based on potential of danger in seismic design, developing basic seismic design calculating the maximum response of a structure using seismic coefficients including those defined using this factor of importance. This idea has been effectively implemented as the basis for seismic design of structures and equipment to this day, and its historical value has been proven. He points out the importance of the reliability of seismic design and the safe design of instrumentation and control in seismic design. Dr. Shibata emphasizes the importance of learning the lessons presented by the damage experienced in earthquakes, the 1995 Kobe Earthquake - yet another example of his invaluable foresight.

Heavy Damage

The 5•12 Wenchuan earthquake was in M8.0, Mianyang felt strongly. Majority of the buildings have varied at different degrees of damage, especially in masonry-frame structures, Which reinforcement cost much higher for repairing; The 1200 buildings in Mianyang city or it’s Suburbs were surveyed. The results showed: masonry suffered much heavier damage and masonry-frame of the mixed structure by designing, which damage were significantly lower than without seismic design. Realization of the earthquake will not be collapsed, and after a simple repair it can be used. Buildings that suffered heavy damage which combined with the relevant code requirements and research in the past, adopt specific measures for strengthening the houses.

This paper reviews the situations and features of earthquake damage to industrial facilities, manufacturing companies, energy supply facilities, and mechanical structures and installations in Japan, and traces trends of countermeasure technology developed focusing on earthquake resistance and vibration control. In Japan, with the 1964 Niigata earthquake as the turning point, earthquake damage to industrial facilities became a social problem. With power stations being constructed in the 1960s, it also became an important technological policy to establish seismic design method for nonbuilding structures such as equipment and piping systems related to nuclear power. The Kobe earthquake in 1995 damaged production companies including leading manufacturers so extensively that it brought a new focus to seismic considerations. We studied the damage to typical equipment and installations and, based on this experience, investigated the features of damage modes to industrial facilities and machinery and considered corresponding technical measures. We present some examples and discuss progressive trends in seismic and vibration control technology following the Kobe earthquake. In particular, we focus on the new seismic design code for high-pressure gas facilities and the development of seismic and vibration control dampers and their applications.
