“…The AISC manual [11] provides formulas for determining the required thickness of the T-stub flange, see Figure 10. The minimum flange thickness t min to avoid the prying force effects is given in Equation (18). Nevertheless, the required thickness to consider the prying force effects is produced when t ≤ t min , see Equation (19):…”

The analytical method for the calculation of the properties of a bolted joint established by the structural Eurocodes proposes the T-stub as a component for the characterization of the tension and compression zones in moment joints. In this article, a review of the state of the art on the T-stub component is developed, where the works developed since it was initially defined, and from the perspectives of formulation, experimentation and numerical simulation are summarized and discussed. Additionally, possible future lines of work are proposed.

“…It was reported that the difference between the experimental results and predicted value reached ratios of 1.73 and 3.0 for plastic and ultimate moment capacities, respectively. Apart from the studies of extended end-plated connections, the studies [20][21][22][23][24][25] conducted for T-stub joints revealed that the Eurocode also underestimates the resistance of T-stub joints.…”

End-plated connections are frequently preferred in beam-to-column connections due to their advantages of high quality and fast assembly. The capacity of the end-plated connections depends on many parameters including the thickness of end-plate and bolt diameter. A comprehensive numerical parametric study was conducted in order to investigate the effects of these parameters on the capacity of the end-plated connections using the finite element tool, ABAQUS. The results of the numerical study were compared with the prediction of Eurocode provision in terms of the capacity and failure mode. The results showed that Eurocode accurately captures the failure modes and predicts the capacity of the connection except for thin plates with high accuracy. However, Eurocode provision significantly underestimated the capacity of the thin-plated extended end-plated connections.

“…However, the tensile action and prying action of the bolt were not measured in the test. Xulin Zhu et al [17] used a piece of extending plate at bolt holes as a thickening measure of the endplate. In this manner, the low bearing capacity of the tapping endplate in thinwalled parts was controlled, and the tensile performance of T-shaped joints was discussed.…”

High-strength blind-bolted T-stub with endplate tapping is a new joint that is applicable to the prefabricated joint of steel columns with closed sections and steel beams. The failure mode and force performance of this joint are affected by many factors. In order to disclose the relations of this joint with various parameters, a calculation formula for the bearing capacity of high-strength blind-bolted T-stub with endplate tapping was proposed. The influences of bolt diameter and plate thickness on mechanical performance, failure mode, and bearing capacity were investigated through a unidirectional tensile performance test on 10 T-stub specimens. A nonlinear finite element simulation of specimens was performed, and its results were compared with those of the experiments. Experimental results show that the bearing capacity of the Tstub specimens is positively related with bolt diameter and plate thickness. Compared with an ordinary high-strength bolt, a new shear failure of tapping thread is added. Finite element analysis confirms that the numerical model is reliable and can provide references for parametric analysis. The ratio of calculated results of the proposed formula to the experimental results ranges from 65.1% to 94.7%, indicating that the calculated results are relatively safe. This study can offer references for the engineering applications of high-strength blind bolts with endplate tapping.
