摘要：

This paper describes a co-rotational formulation for three-dimensional beams in which both the internal force vector and tangent stiffness matrix are consistently derived from the adopted 'strain measures'. The latter relate to standard beam theory but are embedded in a continuously rotating frame. A set of numerical examples show that the element provides an excellent numerical performance. © 1990.
