Optimization Method for Structural Seismic Response Control

Focuses on the seismic response of large-span spatial structure, this paper uses giant magnetostrictive material as the main component to design a kind of new GMM actuator, which could used in active vibration control of large-span spatial structure. The prototype actuator has been produced and the output performance test was carried out. The genetic algorithm has been used to optimize the position of actuators in large-span spatial structure, and the optimization of the results has been analyzed by numerical simulation. The research shows that the GMM actuator has fine actuator effective, and at the same time of improving the computational efficiency of optimization design, genetic algorithm also achieves the overall optimization of the structure and by optimizing the layout of the actuators, the active control of the structure could achieve efficiency and economy.
