On the plastic design of high‐strength steel beams

“…The result was that the plastic resistance moment and a sufficient rotation capacity were achieved by compact sections, leading to the conclusion that plastic design is possible for these sections. Gkantou et al [23] carried out numerical investigations for the ultimate loads of hot-finished square and rectangular hollow sections made of S460 and S690, where true stress-strain curves were de-the past, a rotation capacity R req = 3 was used as a reference value for the limits for cross-section class (CSC) 1 for most structures [3]. However, different structural systems inhibit different rotation requirements, since R req actually depends on the system geometries not being a constant value.…”

Kinematic Hardening Model Comparison of Square Hollow Section Under Cyclic Bending

“…The study can include experimental or numerical analysis-based research. For this SHS, many studies are available: during axial loading (Fang & Chan, 2019), torsion loading (Fadden, 2013), monotonic bending (Wang et al, 2016a;Wang et al, 2016b;Gkantou et al, 2018), combined of axial and monotonic bending (Ma et al, 2019;Arrayago & Real, 2015;Meng & Gardner, 2020;Yun et al, 2020;Zhao et al, 2016), but only a few about cyclic bending and its parametric studies (Fadden & McCormick, 2014).…”

Global buckling of S690 transversely-stiffened plate girders with slender webs: Behaviour and design

“…HSSs are considered as those steels having a minimum yield/proof stress ( y f ) of 460MPa. Recently, they have increasingly been used in different structural engineering applications [1][2][3]. This is because they offer attractive structural solution to heavily-loaded girders and columns owing to their high strength-to-weight ratio.…”
