Joint US/Japanese program of full-size building tests for base seismic isolation.

摘要

Shimizu Corporation of Japan and Argonne National Laboratory of the USA initiated a joint research program on base seismic isolation. The program is centered on testing and analyzing isolation systems in a full-size building and to obtain data on relative response between isolated and nonisolated structures under earthquake conditions. The test facility consists of two identical full-size three-story buildings built side by side, located at Tohoku University in Sendai, Japan. Since April 1989, after the installation of bearings, over 20 earthquake data have been recorded at Sendai test facility. This paper describes the test facility, isolation bearings, observed earthquake records, and responses of isolated and nonisolated buildings under earthquake loads. 3 refs., 15 figs.
