A New Wind Vibration Control Strategy Based on Active Variable Stiffness

Abstract:

Based on the active variable stiffness, a new semi-active control method, whose principal content is using frequency control (FC), is presented. As a new semi-active algorithm, short time maximum entropy analysis is firstly proposed and the exact time and frequency signal at every control short time sequence also is given. The calculation results of a case of a 40-story building showed that the FC method is more effective than the results calculated by the method in the current structural design of tall buildings. The robustness of the algorithm is obtained and the displacement of the structure is reduced effectively.
