Study on First-Floor Isolated Structure with Metallic Damper

Abstract:

As an advancing isolation technology, the first-floor isolated structure can take full use of the first-floor space, and has been promoted in southern China gradually. To study the isolation effect of the first-floor isolated structure and to improve the damping rate of it, a seven-story structural model with laminated rubber bearings and metallic dampers installed on the top of first-floor columns was studied by shaking table tests and finite element analysis using SAP2000 API. The results of the tests and analysis show that the isolation technology with metallic dampers can reduce the seismic response of the upper structure significantly.
