Analysis of a bolted T-stub strengthened by backing-plates with regard to Eurocode 3

Analysis of the behaviour of stainless steel bolted connections

“…The stiffness of a T-stub is defined by considering a continuous beam on four supports; two of these supports are elastic supports representing the bolts' bearing loads considered as applied in their axis [25]. The analytical model of EN 1993-1-8 does not directly consider the interaction between the T-stub and the bolts.…”

“…Unilateral contact is considered under the flange and between the flange and the washer under the bolt head. The flexibility of the bolt due to the contact between the threading and the nut can be taken into account by a fictitious length larger than the real one or by a diameter lower than the real one [25]. In this study, the bolt is considered threaded on a short part.…”

Tensile behavior of high performance structural steel T-stub joints

“…Specifically, the elastic stage stiffness, plastic resistance and plastic stage behavior are analyzed. In the analytical study phase, an analytical approach based on the yield line model [11][12][13] is developed to predict the load-displacement relationships of these joints at small deformation stage. By comparing the test results, the yield line model results and the design equations given by the Eurocodes EN 1993-1-8 [14], the performance of these joints are evaluated.…”

Analytical Studies of Full-scale Steel T-stub Connections Using Delicate 3D Finite Element Methods

“…These response mechanisms are associated with the large variety of connection configurations, geometrical discontinuities, nonlinearconstitutive relationships for base materials, frictional forces that lead to slip, and bolt pretensions that lead to prying action. 13,14) Though the large number of these variables should be taken into consideration, this research attempts to fully understand the response mechanism for the complete behavior of T-stub connections through analytical studies provided by finite element (FE) methods.…”

“…15) Nevertheless, in spite of this profit, the previous FE studies conducted on T-stub connections have been limited to only local T-stub components 7,8,[14][15][16] instead of entire beam-to-column subassemblages. For component tests, the axial loads assumed to be beam-flange forces in the actual connection are only applied to the T-stub components.…”
