| Abstract: | This paper discusses the application of MR damper in the field of wind-induced vibration control of high - rise structure and puts forward a new semi - active control strategy based on the classical LQR theory and the characteristic of MR damper to prove the method for simulating the wind - induced vibration responses of a 40 - story steel structure by computer. The results illustrate that MR damper using semi - active control algorithm can reduce the structural response induced by wind efficiently. |
