| Abstract: | The behavior and strength of tube gusset connections with tube 219×6 and 1/4 annular ribbed plate subjected to eccentric force is investigated. Non dimensionalized ultimate strength interaction relations between the wall moment of tube ,vertical axial force ,and eccentric vertical component force of axial brace force of tube gusset connections with 1/4(1/2) and annular ribbed plate subjected to eccentric force is researched based on the model of equivalent forces of tubular joint. The parameters which influence the ultimate strength of tube gusset joint were analyzed and non dimensionalized ultimate strength interaction relationships were proposed. It is shown that the proposal formula has theoretical and practical significance for design because of comparation with experimentation. |
