An online method for identification and active control of shear type frames with unknown stiffness parameters is presented. The proposed method is composed of two stages. The estimation of the unknown parameters and blind vibration control of the structure take place at the first stage in a relatively short duration. The estimated parameters from the first stage are utilized to enhance the performance of the LQR vibration control algorithm. As a result, the vibration control method is able to tune its internal parameters and improve its performance in the second stage
