Cross-section behaviour of novel stainless steel octagonal hollow sections (OCHS) subjected to eccentric compression

A revised ASCE design interaction curve improves consistency and accuracy in failure load predictions for stainless steel octagonal hollow sections subjected to eccentric compression.

Simulation and cross-section design of steel beams under moment gradients

Moment gradients increase cross-section bending resistances in steel beams in the low to intermediate range, but their positive influence diminishes under high moment gradients.

A novel approach for the optimum cross-section design of thin-walled box section beams subject to oblique bending based on both adequate-strength and local stability conditions

The optimal cross-section design of thin-walled box sections for oblique bending achieves substantial material savings per unit length compared to equivalent designs.

VALIDATION AND PARAMETRIC STUDY OF LEAN DUPLEX STAINLESS STEEL HOLLOW SECTION STUB COLUMNS BY FINITE ELEMENT ANALYSIS

Increasing column thickness increases ultimate load and end shortening in lean duplex stainless steel hollow section columns, while load eccentricity and slenderness ratio have opposite effects.

Machine learning for optimal design of circular hollow section stainless steel stub columns: A comparative analysis with Eurocode 3 predictions

Machine learning models, particularly the SVMR model, can accurately predict the cross-section resistance of circular hollow section stainless steel stub columns, outperforming finite element models and Eurocode 3.

Corner material properties of cold-formed lean-duplex stainless steel sections at elevated temperatures

Corner material properties of cold-formed lean-duplex stainless steel sections deteriorate more severely than flat counterparts at elevated temperatures, with new design curves and stress-strain models being proposed to predict deterioration.

Structural behaviour of LDSS tubular beams with web perforation under three-point bending

LDSS tubular beams with web perforation show improved shear and moment response under three-point bending, suggesting a modification to the European design specification.
