In this paper, the two methods for the finite element analysis of foundation excitation would be proved mathematically equivalent. Although the two methods, i.e. the method of degree-of-freedom transformation and the Lagrange multiplier method, are absolutely different in appearance, but their mathematical essence would be proved completely identical. In other words, although the equations derived from the two methods have different degree-of-freedoms, i.e. the latter much more than the former, while in essence they could be deduced from each other and vice versa. And finally a numerical example will be presented and discussed to demonstrate the correctness of the present theory.
