ROLE OF INCREASED DAMPING WITH VISCOELASTIC DAMPERS IN SEISMIC DESIGN OF BUILDINGS

摘要

The first part of this paper outlines mechanical properties of viscoelastic damper (VED) which are temperature- and frequency-dependent. The second part deals with an analytical method for quantifying damping capacity of a building with the VEDs which are represented by generalized Maxwell models. It has been shown that the damping effect depends on the stiffness of members to support the damper, and that there is an optimum amount of the damper to provide the structure with the maximum damping factor. The third part is to present the availability of the VEDs to assure the ultimate stability of buildings for even quite intense ground motions.
