Abstract
An approach for multiple-model structural control is developed for seismic protection of nuclear power plant, based on active structural control systems. Structural control provides opportunity to realize measures for reduction of seismic vulnerability of high risk structures, like nuclear power plants. The reliability of devices and systems for seismic protection is proved after modelling and simulation of seismic structural control with strong motion real or synthetic seismic signals, maximal close to the realistic ones. In suggested multiple-model system each sub-system corresponds to different actuator or combination of actuators for structural control of different parts of reactor building. After determination of frequency, characteristics, resonances and anti-resonances, is taken decision about reconfiguration of the structural control system. Simulation results for multiple-model active structural control system are shown.
