SEISMIC RESPONSE CONTROL FOR FOUR HIGH-RISE BUILDING STRUCTURES USING CONNECTED CONTROL METHOD

摘要

This paper presents a vibration control method for multiple high-rise buildings against large earthquake motion. This method is called as "Connected Control Method (CCM)" and has the merit of obtaining enough control force to protect high-rise buildings from large earthquakes using passive and semi-active devices. In this paper, first a modeling approach for four scaled building structures is shown and effectiveness of the CCM using LQ control approach for them is demonstrated by seismic response control results. Next, in order to reduce the supplied power, a semi-active control approach in place of active control is applied for the CCM. For this purpose, a new MR damper is developed and designed to have a close performance with results of the LQ control. This performance is verified by measured frequency responses.
