Abstract:
The M 7.4 Miyagi-Ken-oki, Japan, earthquake of June 12, 1978 affected a variety of reinforced concrete structures in the metropolitan area of the city of Sendai. Hundreds of modern structures were su-jected to peak ground accelerations in the range of 0.2g to 0.4g. The duration of the strong motion war more than 30 sec. Peak floor-response accelerations in concrete structures reached 1 .Og. Although several structures were damaged extensively, the performance of the majority of the structures was excellent. The response of several structures is described, including a nuclear power plant; damage is summarized; some strong-motion records are presented; and various causes of damage are examined.
