Abstract：[Objective]To address the passive drawbacks of traditional seismic resistance methods,which rely on the energy dissipation of structural components themselves and tend to cause building damage and collapse,the application methods and effectiveness of the viscous damping wall technology in a practical building were systematically analyzed,with the frame-shear wall structure of a certain library taken as an engineering case.[Methods]Firstly,through the relative movement between the external steel plate(viscous material container)and the internal steel plate(resistance plate),the interlayer deformation was converted into energy dissipation by this technology.Meanwhile,the hysteretic effect between damping force and deformation was utilized to absorb vibration energy,thereby effectively reducing the dynamic response of the structure.Secondly,the hysteretic performance of the viscous damping wall was analyzed through experiments,and the elastic analysis of the main structure under frequent earthquakes was conducted.In addition,the elastoplastic time-history analysis of the main structure under fortification earthquakes and rare earthquakes was also carried out.[Results]Results demonstrate that the viscous damping wall provides robust energy dissipation capacity and adds significant damping to the structure,substantially consuming seismic input and enhancing overall seismic performance.This research offers valuable theoretical insights and practical guidance for similar engineering applications.
