“…In Figure 9, the results from the tensile coupon tests carried out in the present study on both the flat (F) and corner (C) material have been combined with those collated from the literature, reported in references [11][12][13][27][28][29][30][31][32][33][34][35][36], and used to assess the variation of the f u /f y ratio with yield stress f y . The observed trend of decreasing values of f u /f y with increasing yield stress f y is in line with previous findings [8,10,37], and reflects the fact that strengthening mechanisms used in the production of high strength steels bring about significant increases in the yield strength, but have less influence on the ultimate tensile strength [1].…”

“…The ductility requirement based on strain at fracture ε f for high strength steels is examined in Figure 10, where the measured strain at fracture from the tensile coupon tests conducted herein and those collected from the literature, given in references [27][28][29][30][31][32]35], is plotted against the yield strength f y . As anticipated, a general decreasing trend of ε f with f y exists.…”

An experimental investigation into the structural performance of compressed high strength steel (HSS) square and rectangular hollow sections is described in this paper. Both hot-rolled and cold-formed HSS sections were examined. In total six S460NH and five S690QH hot-rolled section sizes and three S500MC, two S700MC and four S960QC cold-formed section sizes were tested. The experimental programme comprised tensile coupon tests on flat and corner material, measurements of geometric imperfections, full cross-section tensile tests and stub column tests. The results of the experiments presented in this paper have been combined with other available test data on high strength steel sections, and used to assess the existing design guidelines for high strength steels given in Eurocode 3. The focus has been on the material ductility requirements, the Class 3 slenderness limit for internal elements in compression and the effective width formula for Class 4 internal elements in compression.Reliability assessments of the Class 3 slenderness limit (both the current value of 42 and a proposed value of 38) and the effective width formula for Class 4 internal elements in compression were carried out. The analysis indicated that, based on the assembled test data considered in this study, and the assumptions made regarding the statistical distributions of material and geometric properties, a partial safety factor greater than unity is required for HSS. Similar findings have also recently been presented for ordinary strength steels.

“…Although the current specifications are able to predict the flexural strength of HSS beams, the existing compactness criteria cannot guarantee the required rotation capacity for HSS members. Previous researches on ultimate bearing capacity, local and overall buckling behavior of HSS columns [20][21][22][23][24] have shown that the effects of initial geometric imperfection and residual stress on the buckling behavior of HSS columns are less detrimental than those on normal strength steel columns. The current steel structure design standards are slightly conservative for HSS.…”

ABSTRACT:Since recent advances of technology in material science and increasing demand for high strength materials, high-strength steel (HSS) has been applied to several landmark buildings and major projects. However, the application of high-strength steel in seismic structures is limited by the relative worse ductility, which usually decreases with the increase in yield strength. In this paper, key issues associated with the application of HSS in seismic structures are pointed out and discussed. The current state of the art of behavior of HSS and recent research on the seismic behavior of HSS carried out at Tongji University are presented. The effect of reheating and cooling during fabrication process on the mechanical properties of HSS is evaluated. Through the revisit and reconsideration on the basic level of seismic design philosophy, two new design methodologies for application of HSS structures for buildings in seismic zones are proposed. Finally, future works related to the application of high strength steels are recommended.
