Abstract：In this paper the difference discrete models of the beam with overhang are established, the stiffness matrices of above discrete system are determined and their sign-oscillating property are proved. On the basis of it, some qualitative properties of the frequencies and modes of the discrete system of the beam with overhang are obtained.
