VERIFICATION EXPERIMENTS OF MEASUREMENT SYSTEM IN FULL-SCALE SEISMIC ISOLATION TEST FACILITY “E-ISOLATION” UNDER CONSTRUCTION

Abstract

A new full-scale seismic isolation test facility named “E-Isolation” has been developed and adopted as a new system that can directly measure the reaction force of the device, excluding the friction force generated in the bearing under the moving platen and the inertial force due to the weight of the platen. In this paper, several experiments were conducted to verify the accuracy of the measurement system in “E-Isolation” under construction. The results of various experiments showed that each component of “E-Isolation” performed as expected in the design, and the measurement system was able to measure data accurately.
