摘要：Beam-to-column connections are very important in steel structure buildings, and have direct effect on safety and economic efficiencies of the buildings. Especially, they have rigidity and ductility that are necessary for behavior and stress transmission of buildings. Furthermore, they are also needed carry 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 applies the model of exponential function based on the equations of equilibrium and compatibility equations at the location of bolts. The prying action reducing both the ultimate load capacity and the fatigue of the bolts are not considered in this study. The elasto-plastic behavior has been studied through various models 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 a useful tool for the design of T-stub connections
