Abstract EN
The damping ratio of an added-story frame structure is established based on complex damping theory to determine the structure seismic response.
The viscous dampers are selected and arranged through target function method.
A significant damping effect is obtained when a small velocity index is selected.
The seismic responses of a five-floor reinforced concrete frame structure with directly added light steel layers and light steel layers with viscous dampers are compared with the finite element software SAP2000.
Calculation results show that, after adding the layers, the structure becomes flexible and the shear in the bottom layer decreases.
However, the interlaminar shear of the other layers increases.
The seismic response of the added layers is very significant and exhibits obvious whiplash effect.
The interstory displacement angles of some layers do not meet the requirements.
The seismic response of the structure decreases after the adoption of viscous dampers; thereby seismic requirements are satisfied.
