Parametric finite element study of slotted end connections to circular hollow sections

Parametric finite element study on slotted rectangular and square HSS tension connections

“…Experimental and numerical studies of round slotted HSS connections have also been conducted by Cheng et al [10] and Martinez-Saucedo et al [11]. Finite element analyses from these studies were able to closely predict the load versus deformation curve of the test.…”

“…This approach has been used by Cheng et al [10] and Martinez-Saucedo et al [11] in the finite element analyses of round slotted HSS. An approximation of the critical equivalent plastic strain limit can be calculated from the measured cross-section area ratio at fracture as…”

“…In both Eqs. (10) and (11), F u is the ultimate strength of the flat segment of HSS. Comparisons of the test and predicted net section efficiency for specimens by Huang [7] are listed in Table 3.…”

Tensile Behavior of Welded Tee End Connection for Circular Hollow Members

“…In both the codes, stresses in the tube are calculated assuming a load diffusion slope of 60° within the thickness of the cap plate (Figure 2a). However, according to other authors [4][5][6][7][8], the assumption of a distribution slope equal to 2.5:1 [2] have to be used and therefore the diffusion angle of 68° is used. Independently from the diffusion angle, the effective length for load diffusion l e can be computed by the following equation:…”

“…It consists of a slotted end connection and a gusset plate welded to the tube by means of a corner weld. For this connection all the design rules reported in International Specifications are based on a consolidated literature [3][4][5]. From the structural point of view it is certainly more efficient but also more expensive than the connections showed in Figures 1a and 1b.…”
