“…We can design our buildings in such a manner that they can absorb the power of sudden shocks to have minimum loss. Nowadays rocking structural systems are developed with yielding base, which reduces seismic responses of buildings by creating rocking vibration during strong earthquakes [17][18][19]. A yielding base is one that displaces sufficiently to minimize the devastating effect during strong earthquakes.…”

The present study aims to study the propagation of Rayleigh-type wave in a layer, composed of isotropic viscoelastic material of Voigt type, with the effect of yielding base and rigid base in two distinct cases. With the aid of an analytical treatment, closed-form expressions of phase velocity and damped velocity for both the cases are deduced. As a special case of the problem it is found that obtained results are in good agreement with the established standard results existing in the literature. It is established through the study that volumeviscoelastic and shear-viscoelastic material parameter and yielding parameter have significant effect on phase and damped velocities of Rayleigh-type wave in both the cases. Numerical calculations and graphical illustration have been carried out for both the considered cases in the presence and the absence of viscoelasticity. A comparative study has been performed to analyse the effect of layer with yielding base, traction-free base and rigid base on the phase and damped velocities of Rayleigh-type wave.
