SHAKING TABLE TEST OF STRUCTURAL MODEL WITH VISCO-ELASTIC DAMPER
|
´˜^i‰pjF
This paper aims at showing the availability of visco-elastic damper in decreasing the earthquake-induced vibration of a building. It includes a shaking table test and an analytical study to confirm it. A damper is composed of a pair of parallel steel plates and a layer of epoxy visco-elastic material between them. Seismic response of a building with the damper has been found to be less than half the response without the damper. The response is accurately simulated by the analysis using three-element spring-dash model to represent the mechanical properties of the damper.
