Viscoelastic Structural Damper

Application ID: 30871

Viscoelastic dampers are frequently used to protect tall structures against vibration. The Viscoelastic Structural Damper application can perform the time-domain and frequency-domain analyses for a typical viscoelastic damper. The purpose of the app is to compute and analyze the important parameters of the damper such as the hysteresis loop and loss and storage moduli for a prescribed material model. In addition, the application provides a visual comparison of the damper behavior when you use two different settings for the viscoelastic material parameters.

You can change the number of viscoelastic branches and their corresponding material parameters as well as the magnitude and phase of the applied load. The app can be used to study the damper over a range of frequencies or as time-dependent problem.

This application example illustrates applications of this type that would nominally be built using the following products:
