摘要：

A general format, based on equilibrium states, is developed for the stiffness matrix of elastic beam elements. The stress states are described relative to the line connecting the element end points, whereby the external work takes a common form independent of the shape of the beam element. The resulting stiffness matrix is obtained by simple, explicit combinations of a small number of stress energy terms. Examples include a Timoshenko beam with flexible joints, a beam of variable cross-section, and a strongly curved circular beam.
