| Abstract: | By introducing element property matrix of elastic foundation beam and integrate constant matrix, it is proved that the two matries are convere matrixes each other so that finding the solution of elastic foundation beam becomes simple and clear. The method presented and used to determine element stiffness matrix and fixed ended element forces of elastic foundation beam caused by loads is clear in physical conception and simple in programming, and can be used in finite element structural analysis. |
