In this paper, simulating the wind induced responses of a building structure using a linear mass shaker is presented. The shaker force is calculated by using the inverse transfer function of a target structural response to the actuator. Filter and envelop function are used such that the error between wind and exciter induced responses is minimized by preventing the shaker from exciting unexpected modal response and initial transient response. The analyses results from a 76-story benchmark building problem in which wind load obtained by wind tunnel test is given, indicate that the linear mass shaker installed at a specific floor can approximately embody the structural responses induced by the wind load applied to each floor of the structure. The linear mass shaker signal is generated by the proposed method can be effectively used for evaluating the wind response characteristics of a practical building structure and for obtaining an accurate analytical model of the building under wind load.
