| Abstract: | A global stability analysis of three-dimensional frame structures is conducted on member systems by finite element method; and a stable stiffness matrix is derived for the space plastic hinge element. The method will be suited to space frame structure of any state, and the load displacement curve of which will be given. The numerical results tally with experimental data. |
