Abstract
The paper deals with the formulation of semiactive controllers for a class of nonlinear seismically excited base-isolated structures in order to reduce the absolute motion of the base and the inter-story drifts of the building structure. The advantage of the proposed control scheme is that semiactive control devices are only required at the base and the first floor to adjust on-line the damping and stiffness using their displacements and velocities as feedback information. The feedback control l...
