Abstract—Horizontal vibration of a rigid circular foundation rested on the top of a transversely isotropic half-space is presented. By using fundamental Green’s functions and applying Hankel integral transform in the radial direction and Fourier series the problem may be changed to a system of four separate integral equations, which, in turn, are reduced to a pair of Fredholm equation of the second kind. Under dynamic excitation, the related compliance function are numerically evaluated. The present solutions are analytically and numerically in exact agreement with the existing solutions for a half-space with isotropic material.
Index Terms—Horizontal vibration, rigid foundation, dual integral equation, transversely isotropic half -space, green’s function.
