Response observation of scaled model structures to strong earthquakes

Abstract Scaled model building structures with intentionally reduced seismic strength from one-third to one-half were constructed in 1983 for long-term observation in order to collect earthquake response data and research failure mechanisms during earthquakes. A monitoring system was installed in the structures as well as in the surrounding soil. Since then, a great deal of data has been recorded for many earthquakes. Among them, various kinds of data describing response behavior during four strong earthquakes were successfully collected. These data are examined in this paper. Some tentative conclusions are drawn for elastic-plastic behavior, interactions between structures and soil, and soil behavior.
