Sep 30, 2020 · A seamless S890QL high-strength steel pipe was used in this study, with a diameter and thickness of 140 mm and 6.5 mm, respectively. The chemical composition of the S890QL pipe product is shown in Table 2, and the relevant upper limit values (Ref 1) are also listed.The mechanical properties were determined from tensile coupon tests conducted in accordance with the international standard EXPERIMENTAL STUDY OF MECHANICAL BEHAVIOUR OF May 12, 2017 · Advanced Steel Construction an International Journal. ABSTRACT. Compared with the lower-grade steel members, the application of steel angles made of Q420 greatly reduces the self-weight of lattice transmission tower and further leads to the saving of foundation cost. Experimental investigation and modeling on residual stress This paper reports an experimental study of the residual stresses of Q420 HSS (high strength steel) large-section angles by the sectioning method, including two hot-rolled angles and two
Download Citation Experimental study on overall buckling behavior of Q420 high strength equal angle members under axial compression The Q420 high strength angles with the nominal yield Fatigue Life Behaviour of Transverse Fillet Weld and This study deals with the fatigue life assessment of the transverse fillet weld and transverse fillet weld on weld fatigue specimen of the offshore steel S460G2+M with a thickness of 10 mm. These specimens were joined using gas metal arc welding (GMAW) with ER80S-N1 filler metal of 1.0 mm in diameter and mixed gases of 80% Ar + 20% CO2 as the consumables. Fatigue strength of filletwelded joints at subzero While detrimental effects caused by high tempera-tures are well covered in literature and are addressed in international standards, few publications exist on the fatigue properties of welded steel joints for subzero temperatures.2-10 Moreover, most of those studies focus on fatigue crack growth (FCG) rate testing for cryogenic applications.
