Abstract

The finite element (FE) equations of motion with fractional differential operator term has been developed by Shimizu and Zhang for analysing the dynamic behavior of viscoelastic structures. In this formulation the authors derived the new "viscoelastic damping matrix (VDM)" which evaluates the damping character for the viscoelastic structures. The present paper investigates the validity of the FE equations with "VDM" by comparing with the results of the experiment conducted for evaluating the viscoelastic seismic damper.
