Numerical Investigation of Visco-Elastic Damper for Seismic Vibration
Dynamic response of structures is of extreme importance for the evaluation of seismic behaviour of structures. In vibration analysis, we are generally concerned with damping in terms of system response. The energy absorption devices increase the damping of the structure by plastic deformation or by viscous resistance of devices such as visco-elastic dampers. For structures subjected to dynamic loading, it is excited by a suddenly applied non-periodic excitation as transient response, since steady-state oscillations are not generally produced. Such oscillations take place at the natural frequencies of the system with the amplitude varying in a manner dependent on the type of excitation. The response of visco-elastic dampers under transient loading for seismic vibrations has been examined in this study. A finite element model is created using numerical software ANSYS for studying the response of visco-elastic damper. From the analysis, it is clear that shear strain is maximum in the visco-elastic material such that during earthquake vibrations, the rubber will absorb the energy and the damage is reduced in structures.
