A numerical-informational approach for characterising the ductile behaviour of the T-stub component. Part 1: Refined finite element model and test validation

Tensile behavior of high performance structural steel T-stub joints

“…(12) to (16) depends on the geometry of the joint (m, n and the size of bolt but not the plate thickness t) [22] and the steel grade used to fabricate the joints. To obtain the value of K, first differentiate the elastic state expression in Eq.…”

“…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.…”

Structural Behaviour of Beam to Concrete-filled Elliptical Steel Tubular Column Connections

“…S355 steel was adopted for the EHS columns and beams with a nominal yield strength of 355MPa and a nominal minimum ultimate strength of 470MPa [20] while S275 steel was selected for the fin plates which has a nominal yield strength of 275MPa and nominal minimum ultimate strength of 410MPa. True stress-strain relationships were converted using the equations where E2=σu was assumed [21]. The three-part linear stress-strain curve was adopted for steel.…”

Tensile behavior of cruciform stubs with four bolts per row

“…The component method is the preferred design theory for these semirigid beam‐to‐column connections at room temperature [ 18–20 ] and elevated temperature. [ 21,22 ] It divides the joint into several components, such as angles under tension and bending column flanges.…”
