This work explores symbolic and numeric solutions to the Lyapunov matrix
equation as it applies to performance-based assessment of base-isolated structures
supplemented by modified bang-bang control. Traditional studies of this type rely on
numeric simulations alone. This study is the first to use symbolic analysis as a means
of identifying key "cause and effect" relationships existing between parameters of the
active control problem and the underlying differential equations of motion. We show
that symbolic representations are very lengthy, even for structures having a small
number of degrees of freedom. However, under certain simplifying assumptions,
