The Seismic Performance Analysis of Steel Frame Adding the Viscoelastic Dampers

Abstract:

Based on the mechanics characteristics of the viscoelastic dampers, the seismic performance of a 5 layers steel frame structure with viscoelastic dampers or not was researched. In under the action of the rarely met earthquake, the finite element analysis software MIDAS was used to analyses two of the models of displacements, interlayer shear and ductility of structure. The results showed that: after the installation of viscoelastic dampers, the displacements and interlayer shear of the structure reduced significantly, and ductility increases, the earthquake response can be cut down obviously, it shows better seismic performance.
