This paper investigates the dynamic properties of a viscoelastic seismic dampar by means of experimental test and the finite element analysis (FEA). A manufactured viscoelastic seismic damper (VESD) was tested and the data were obtained for investigating vibration characteristics. The results of the test were summarized for the following items, i.e. as histeresis loop, damping capacity , equivalent damping coefficient, and equivalent spring constant. The FEA with fractional derivative model was also conducted and the results of computation were obtained for the same items by using the parameters obtained from the dynamic test for the used material. The remarkable correlation between the test and the FEA has been observed. Hight performance of the viscoelastic damper is also shown.
