Unified hybrid stress finite element approach for dynamic deformation problems of plane frame structures have been formulated, and its excellent promising potentialities for the dynamic problems as well as the static have been verified with several numerical tests in the previous reports. In this paper, the hybrid stress finite element method/procedure for free vibration problem of space frame structures is presented. For the space frame structures with rigid, pin and/or semi-rigid connections, the specific construction of the free vibration problem as compared with the static and the outline of the present approach are referred and summarized, and the hybrid stress finite element formulation for the space beam-column under consideration is developed. Using the polynomial expansions for the resultant stresses, a new series of space beam-column elements for the free vibration analyses is derived. Several numerical tests are performed, and show that the present approach have the good accuracies and convergencies for free vibration problem of space frame structures.
