An efficient numerical method is presented for analysing in-plane waves in layered halfspace. The geometry considered is a layered soil with arbitrarily distributed properties underlain by an elastic 'subgrade' which extends to infinity. Two alternative subgrade models have been developed with respect to material properties: (a) a uniform subgrade where properties are constant, and (b) an inhomogeneous subgrade where elastic moduli vary with some arbitrary power of depth. Comparisons made for the uniform subgrade case indicate the efficiency of the newtechnique. Some results are also presented for the inhomogeneous subgrade case for which there is no analytical solution available.

Forced asymmetric vibrations of an axisymmetric structure in contact with an elastic half-space are investigated by means of an extended version of the Global-Local Finite Element Method (GLFEM). In GLFEM, the structure and part of the surrounding medium are modeled by conventional finite elements.
