Summary

Beam-to-column connections are very important in steel structure buildings, and have a 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. They must also have strength and the ability to withstand strain as well as being easy to construct. The design and analysis of steel structure connections are generally considered to consist of rigid, semi-rigid or pin joints. The deformation characteristics of H-shaped beams with new T-stub connections are investigated, in this paper, including the effect of these joints on the inelastic behavior of the beams. This research is applied to the model of the exponential function based on the equations of equilibrium and compatability equations at the location of bolts. Prying action is not considered reducing both the ultimate load capacity and the fatigue of the bolts in this study. The elasto-plastic behavior has been studied using various models with parameters such as the length of the T-flange, distance of bolts and the diameter of bolts. The results indicate that the distance of the bolts has a great effect on the ultimate strength and deformation capacity of T-stub connections. The method presented may be a useful tool for the design of T-stub connections.
