In this paper, a semi-active structural control system, which incorporates a magnetorheological damper, is devised, built, and implemented in a two-degree-of-freedom shear frame model. First, parameters of the damper model are identified based on the Bouc-wen model using test data. Furthermore, two control systems, including the skyhook and PID, are implemented in the
structure. The performance of the control systems is then evaluated via shake table tests for a sample earthquake. Experimental results reveal that the skyhook control system can successfully mitigate the transmitted accelerations to the floors. As a result, the base shear is considerably decreased. Furthermore, it is shown that performance of the proposed PID control system is quite comparable with that of the ideal skyhook one, implying successful performance of the PID controller in tackling the seismic disturbance.
