This paper presents the problem definition and guidelines of the next generation structural control benchmark problem for seismically excited buildings. Focusing on a 20-story steel structure representing a typical mid- to high-rise building designed for the Los Angeles, California region, the goal of this study is to provide a clear basis to evaluate the efficacy of various structural control strategies. An evaluation model has been developed that portrays the salient features of the structural system. Control constraints and evaluation criteria are presented for the design problem. The task of each participant in this benchmark study is to define (including devices, sensors and control algorithms), evaluate and report on their proposed control strategies. These strategies may be either passive, active, semi-active or a combination thereof. A simulation program has been developed and made available to facilitate direct comparison of the efficiency and merit of the various control strategies. A sample control design is given to illustrate some of the design challenges.
