Semi-active Control of Base Isolation with Energy Transition Control Device

The semi-active control of base isolation with energy transition control divice(ETCD) is established by installing the ETCD between the isolation floor and the ground. Theoretical models of the ETCD and the control system are finished and the numerical simulation for responses of the system excited to earthquake is represented. The results show that the ETCD can transform partial seismic energy to hydraulic energy, and the energy can be used in further control.
