Aktiver Erdbebenschutz für mehrstöckige Gebäude

A multi-storey building is fit with an actor and a base isolation system for the purpose of active earthquake protection. The whole system is described by a nonlinear mechanical model, that takes hysteresis into account. The active damping is provided by a nonlinear control law, which is designed following the theory of Liapunov. The principle of invariance is used to prove the stability of the control loop. Simulations for an artificial earthquake show, that the proposed protection is applicable for real buildings.
