摘要

Use C_(nv) group decomposes distributed polynomial into the orthogonal functions in periodic region, and the periodic function is approached by those orthogonal functions. The structure of beam is expanded to periodic region and additional forces is added to the beam to make the displacement of beam to be periodic function, and therefore the displacement can be approached by those orthogonal function. Efficient of the partial defined function are gotten by the Rice method, and the additional forces is determined by boundary condition. This method is elementally to be finite element method. Because of using the orthogonal function the calculation is greatly reduced, the calculation is similar to method of boundary element.
