In this paper, a design and calculation method of semi-active seismic response control of tall buildings with podium structure coupled by ER / MR intelligent damper is established. In this paper, based on the derivation of ER / MR intelligent damper model, the basic equation of seismic response of ER / MR intelligent damper coupled with podium building is established. According to the principle of instantaneous optimal active control, A semi-active control strategy based on optimal active control displacement with ER / MR intelligent damper coupled seismic response of tall buildings with podium is proposed. The simulation results of the controlled seismic response of the 20-story and 5-storey podium building using this method show that the semi-active ER / MR intelligent dampers coupled with the main building and the podium can effectively restrain the high-rise buildings with podium Whiplash Effect on Structural Seismic Response. And can uniformly reduce the seismic response of various layers of the structure. It is a simple, convenient and effective intelligent control device.
