Abstract
A hybrid experimental method, in which an actuator-excited vibration experiment and a response analysis using a computer are combined on-line and conducted simultaneously, is being developed as a new seismic experimental method for investigating structural systems.In this report, a mehtod using a shaking table as the actuator is proposed so that the hybrid experimental method can be applied to a secondary structural system attached to a primary structural system.A response analysis algorithm is proposed for this experimental method and its stability and calculation error are investigated by using a rigid mass as a secondary system.In addition, the feasibility of this seismic experiment was demonstrated by using an experimental system consisting of a small shaking table and a digital signal processor.
