Shear behavior of fin plates to tubular columns at ambient and elevated temperatures

Modeling of CFRT through-diaphragm connections with H-beams subjected to axial load

“…Between 14% and 23% of the total capacity of the connection comes from the membrane action at the ultimate deformation, which cannot be ignored in the analysis. This was further verified by Jones [20] through analysis of the results of an extensive set of numerical simulations.…”

“…According to Jones's study [20], the failure of the steel wall could be assumed to be made by 50% pure membrane action and 50% yield line mechanism. This was validated by Jones [20] by investigating the stress distribution across the cross-section of the column wall both at the center of the loaded wall and at the column wall edge. The stress distribution through the column wall thickness was re-depicted in Fig.…”

“…Angle between the diagonal line (e.g., line [19][20][21][22][23][24] and the horizontal line θ 1 ,θ 2 Angle between the deformed plate of the steel tube and the original plate θ 3 Angle between the plates 1-21-18-6 and 1-6-7-4 Plastic moment of steel tube wall, per unit length, without preload (= f ys t s 2 /4) n Axial load ratio of the concrete-filled RHS column (= N/ (f ys A s + f cu A c )) N Axial load applied on the column P y Ultimate failure load of the through-diaphragm connection under tension load P yn Ultimate failure load obtained from the numerical analysis by Lu (1997) …”

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

“…Fin plate connections have been widely adopted owing to the merits of easier erection, rapid construction and lower cost. Jones [6] studied the behaviour of single-sided fin plate to steel tubular columns loaded by tensile and shear force. Parameters including column cross-section shape (CHS and RHS), column and fin plate thickness, concrete infill, elevated temperatures and lever arm were considered.…”
