The purpose of this study is to find a feasible feedback comfort control function for building structures which are subjected to wind force excitations. A vibrational model of multistory building structures subjected to wind force excitation and comfort control was formulated, and solutions were obtained with the use of the Monte Carlo method. An effective and feasible comfort control law was found and applied to a 40-story steel building structure. Results of the analysis showed that: (1)The comfort control law performed satisfactorily according to the comfort and safety criteria; and (2)it was practically feasible to use such an active control law in designing future building structures.
