Earthquake simulation tests on a weak-layer steel frame equipped with EDD

In this paper,a five-story steel-frame model is designed and constructed,which is added three types of energy-dissipation dampers(EDD) in its weak layers,namely friction damper,viscoelastic damper and friction-viscoelastic damper.Shaking table tests of the steel frame model simulating the freguent and the rare earthquakes are conducted.The tested results show that the EDDs are effective in attenuating seismic response of the frame model.
