| With the development of social economy and technology, speeding up the process of urbanization, increasing the number of high-rise buildings, structure height increase by leaps and bounds. China is an earthquake prone country, huge losses to China caused by the earthquake disaster. Therefore, research of high-rise building structure in Shock absorption is very necessary. In view of the fact that China is still a developing country with the basic national conditions, this paper drawing on a wide range of domestic and foreign research results on the basis, we studied suspend structure which is a economical and effective damping system.Research content mainly as follows:(1)Using MATLAB software,we made a optimization design for a single-layer suspended mass pendulum vibration.the MATLAB GUIDE is very intuitive to display the optimization process and results. The results show that the numerical search method to structure the suspended pendulum optimization, structure vibration response has been greatly weakened; structural vibration response is related to mass ratio and frequency ratio of the pendulum and the structure, damping effect with mass ratio increased with the increase, but more than a certain value (in this example is 0.1), the damping effect is more and more small, when the frequency ratio is close to 1, the structure has the best damping effect.(2)The method of the single-layer suspended mass pendulum vibration optimization is used for a 30 story high-rise building of Pendulum damping optimization control. Results show that:under the action of earthquake, the damping effect of the high-rise structure is still evident, by using the optimization method we can makes the structure to achieve the optimal damping effect; high-rise structure under earthquake seismic response is related to mass ratio and frequency ratio of the pendulum and the structure,which is consistent with the calculation result of the single-layer suspended mass pendulum. |
