BIFURCATION OF SPACE FRAMES.
Abstract
A finite element for a prismatic member subjected to axial loads is derived for the stability analysis of elastic spare frames. The derivation is based on the face that in a stable state of equilibrium the second variation of the total energy is positive definite. A feature of the element developed is that the reduction of torsional rigidity due to the presence of axial stresses is taken into account. Several examples are presented. An excellent agreement with analytical results is obtained, where closed form solutions are available. (Author)
