Potential improvements in seismic disturbance rejection to be obtained by using active variable damping control in a structure are evaluated. Using the responses to seismic excitation of an optimally controlled variable structure and of a minimax optimally designed fixed structure, the authors obtain an upper bound on the achievable performance and a lower bound on the acceptability of a control system for a variable-damping structure.
