In this paper, draw the idea of beam unit, the bias along the vertical box is divided into a number of oblique beam. On the basis of analysis of the displacement, through positive and oblique coordinate transformation relations, and directly built on the oblique coordinate system to describe the methods of displacement unit space. With potential energy principle is derived in oblique beam element stiffness matrix and the establishment of the finite element formulation. The preparation process of the finite element analysis is used to verify the structure of bias.
