A method is proposed to control seismic response of a high-rise building considering function maintenance of an elevator. When a cost function for optimal control is formulated to reduce response of rope, response of a building deteriorates especially in high frequency range. In order to overcome this drawback, the proposed method employs frequency shaping linear quadratic Gaussian control and variable gain feedback. Time history analysis is carried out using simulated ground motion and it is verified that the proposedmethod can reduce the response of both a building and rope effectively.
