The superiorities in accuracy and efficiency of this technique are shown by comparing the simulation results with those obtained with the Davenport target spectrums. The model of a 76-story 306 m-high reinforced concrete structure recommended by the second generation benchmark vibration control for building is studied. Numerical results of the structural dynamic-response to the tuned-mass-damper(TMD) control and the linear quadratic Gaussian(LQG) control are obtained respectively. %K fluctuating wind %K stochastic simulation %K AR model %K high building %K time-history curve %K wind-induced vibration control
