Axial capacity of circular hollow section T-joints using grade HSB 600 steel

Structural behaviour of T-joints between high strength S690 steel cold-formed circular hollow sections

“…For those T-joints under brace in-plane moments, the critical failure mode is typically a section failure of the braces under in-plane moments while local plastification in the welded brace/chord junctions may become apparent. A total of four T-joints between hot-finished CHS under brace axial compression were tested and reported by Choi et al [7], and the measured yield strength of these CHS was 517 N/mm 2 . All these four T-joints failed in local chord plastification.…”

Experimental investigation of CHS T/Y‐joints fabricated from high‐strength steel

“…Tab. 8 summarises the information on the database collected in this study [6,[29][30][31][32][33][34][35][36][37]. The database mainly consists of experimental data.…”

“…Unfortunately, this was not possible for most data except for those of Lan et al [6] and this study because of the lack of necessary information. For the database lacking 3 % indentation information [29][30][31][32][33][34][35][36][37], the peak load was selected as the ultimate strength. The difference between the peak load and the 3 %d 0 limit-based ultimate strength is marginal in most mild steel joints [8], but it can be appreciable in more flexible HSS joints (see Fig.…”
