Through the study of viscous damping wall at home and abroad, and the main contents of this paper, the calculation formula and the mechanical model, so as to lay a good foundation for calculation and analysis. Secondly, the analysis to determine the model structure, the structure of the modal analysis in without control, period, frequency and vibration modes of the structure determined. Finally, in order to study the viscous damping wall in high-rise reinforced concrete frame structure vibration control, In this paper on the basis of modal analysis, setting viscous damping walls in the corresponding location, using the method of FNA in the software of Sap2000, carries on the analysis on the vibration of structure under different conditions, through the comparative analysis, this paper obtains: the viscous damping wall has significant damping to the structure, and the damping effect increases with the number of viscous damping wall, Additional damping force of viscous damping wall increases with the increase of earthquake acceleration, through comparative analysis of different working conditions, the additional damping wall centralized configuration in the below of the structure, can achieve more damping effect. |
