Focuses on the stress and deformation characteristics of spatial latticed structure in earthquakes, this paper uses giant magnetostrictive material as the main component to design a kind of new GMM active rod, which could used in active vibration control of spatial latticed structure，and the output performance test was carried out. The genetic algorithm has been used to optimize the position of GMM active rods in spatial latticed structure, and the optimization of the results has been analyzed and confirmed by Numerical simulation of typical example and an earthquake simulation shaking table test research to a Kiewit shell model structure. The research shows that the GMM active rod has fine actuation effective; the optimal control method could improve the efficiency of spatial structure active vibration control. It also shows that the GMM active rods with optimal control method to spatial structure were effective, and the active control of the structure could achieve efficiency and economy.
