Development of Real-Time Hybrid Experimental System using a Shaking Table : 2nd Report, Feasibility Study with a Single-Degree-of-Freedom Secondary System

Abstract

A hybrid experimental method, in which a vibration experiment using an actuator and a vibration analysis using a computer are simultaneously conducted by exchanging information with each other, is being developed as a new seismic experimental method for structural systems. We have proposed using a shaking table as the actuator so that the hybrid experimental method can be applied to a secondary structural system attached to a primary structural system, and we have made an experimental system consisting of a small shaking table and a digital signal processor. In the work described in this report, this experimental system was applied to a single-degree-of-freedom secondary structural system attached to a primary structural system, the feasibility of this seismic experiment was demonstrated by comparing the results obtained from the hybrid experiment with those obtained from analysis of the whole structural system.
