【Abstract】 This paper, based on the generalized variational principle, analyses the beam on elastic founda-tion. The undetermined parameters are the nodal deformations and the nodal rotating angles. The papercalculates the internal force work and the external force work by using the interpolating functions andnumerical integration each. This method proves to be very simple. The calculating results show that themethod has strong principle, high accuracy and is simple for handwork. It is also easy to performby microcomputer.更多还原
