For the unified analysis of skeletal structures and foundations, a one-dimensional finite element for the foundation is formulated. This is achieved by assuming the same displacement field for the foundation as that used for the beam. The foundation is assumed to be of the Winkler type but it offers resistance not only to normal forces but to shear and torsional ones. The new foundation stiffness matrix is easily incorporated into existing structural analysis computer programs. Numerical examples are given. They include single members on or in an elastic medium and general skeletal structures partially or fully buried underground. Accurate and efficient solutions are obtained.
