Abstract :
In this paper, attenuation zones of two-dimensional periodic rubber concrete panels are investigated. Both the Bragg-scattering periodic panels and the Local-resonant periodic panels are studied. It is found that complete attenuation zones in the low frequency region can be obtained in the considered panels by proper design. Further, parameter studies show that non-symmetric periodic panels with directional attenuation zones are much suitable for engineering applications. Numerical simulation shows that vibration attenuation is possible if the frequency of an excitation falls within the attenuation zones. The present investigation also shows that vibration can be reduced significantly by using a periodic structure with only three units. The results of the study provide valuable information for a better understanding of dynamic properties of periodic rubber concrete panels.
