An experimental and numerical study of square and rectangular slotted HSS connections

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

“…Numerous tests on rectangular (RHS) and square (SHS) slotted HSS tension members have been carried out by Zhao and Hancock [3], Korol [4], Zhao et al [5], Wilkinson et al [6], Huang [7] and Zhao [8]. All specimens tested by Zhao …”

“…Test data from Huang [7] and Zhao [8] were used extensively in the development and validation of the finite element model for the parametric study. Thus, a brief description of these two test programs is provided.…”

“…Square and rectangular slotted HSS tension specimens with and without end welding were tested by Huang [7] and Zhao [8] respectively. Sections used in these test programs consisted of ASTM-A500 Grade C HSS 89 × 89 × 4.8 and HSS 127 × 51 × 4.8, cold-formed non-stress relieved tubular sections.…”

“…All analyses were carried out using a material user-subroutine that models isotropic hardening so that the analysis can be terminated automatically when the ε p c limit is reached. Specimens from Korol [4] and Huang [7] were modelled. Numerical simulations of specimens from Huang [7] were carried using the true stress-true plastic strain curves in Fig.…”

“…Specimens from Korol [4] and Huang [7] were modelled. Numerical simulations of specimens from Huang [7] were carried using the true stress-true plastic strain curves in Fig. 5 and the generated curve for a higher strength HSS corner using parameters in Table 2.…”
