An approach is presented to stiffness–damping simultaneous optimization for displacement–acceleration simultaneous control. To make a shear building model stiffer, the sum of mean‐square interstorey drifts to stationary random excitations is minimized or the mean‐square top‐floor absolute accelerati...
