This paper presents an overview and problem definition of a benchmark problem for the response control of wind-excited tall buildings. The building considered is a 76-story 306 meters concrete office tower proposed for the city of Melbourne, Australia. The building is slender with a height to width ratio of 7.3; hence, it is wind sensitive. Either active, semiactive or passive control systems can be installed in the building to reduce the wind response. In the case of active control systems, either an active tuned mass damper (ATMD) or an active mass driver (AMD) can be installed on the top floor. In the case of passive or semi-active systems, such as viscous dampers, ER/MR dampers, etc., control devices can be installed in selected story units. Control constraints and evaluation criteria are presented for the design problem. A simulation program based on the LQG has been developed and made available for the comparison of the performance of various control strategies.
