Abstract

Viscoelastic damper can effectively reduce the response to structure because of the wind vibration and earthquake;it is a very important link to determine the stress-strain relationship of viscoelastic materials.The stress-strain relationship of viscoelastic materials for harmonic dry scratching input oval is relatively complex.In order to simplify the calculation,this paper introduces a kind of method to simplify the oval stress-strain relationship.Combining with curve fitting experience,it presents viscoelastic materials stress-strain constant simplified calculative formula.
