Abstract: In consideration of the difficulty in controller designing of high-rise structures due to the high rank of its model, balanced reduction is adopted to reduce the rank. An equation of state is formed by several modes with higher controllability and the contradiction between high rank of control object and low rank of controller. Seismic acceleration in a short period is predicted by RFF online. Thus, a predictive model with the consideration of time delay is founded before procurement of structural predictive control. Then the response of an 11-stories frame is analyzed, the numerical example is presented to show that the responses are reduced effectively and robust.
