结构振动控制中控制力的最佳位置

In building structures seismic area, more and more civil engineering buildings are taking the long-span and high-rise form and the higher requirements for structural safety and comfort performance are needed. Traditional seismic technology has certain limitations on the cushion structures. The theory of modern structural control puts forward the concept of the vibration control of civil engineering structures in order to determine the optimal control force vector under the optimal control objective. For the optimal control position, Shaking table experiments and seismological records show that the force is better placed on the roof of building. In this paper，the optimum location of control force in the building structure is obtained according to simplification and numerical analysis of the equation of motion.
