Beam-to-column connections are very important in steel structure buildings, and have direct effect on safety and economic efficiency of the buildings. Especially, they have rigidity and ductility that are necessary for behavior and stress transmission of buildings. And it also needed for them to carry the ability of strength and strain with easy construction. The design and analysis of steel structure connections are generally considered to consist of rigid, semi-rigid or pin joint. Deformation characteristic of H-shaped beams with newly T-stub connections is investigated for the effect of these joints on inelastic behavior of the beams in this paper. This research is applied the model of exponential function based on the equations of equilibrium and compatability equations at the location of bolts. It is not considered that prying action reducing both the ultimate load capacity and the fatigue of the bolts in this study. The elasto-plastic behavior has been studied through various model with parameters of the length of T-flange, distance of bolts and the diameter of bolts. The results indicated that the distance of bolts has a great effect on the ultimate strength and deformation capacity of T-stub connections. The presented method may be an useful tool for the design of T-stub connections. |
