Summary: The current steel design standards do not differentiate between square and rectangular hollow sections (SHS and RHS) members cold-formed by different approaches, which can lead to underestimation of member strength. Research shows that direct-formed SHS/RHS members exhibit better stub column behavior than indirect-formed ones. Post-cold-forming galvanizing can effectively improve the residual stress and stub column behavior of direct-formed SHS/RHS. Further studies suggest modifications to the existing design rules for SHS/RHS stub columns to account for the differences in behavior between direct-formed and indirect-formed sections.

Summary: This paper addresses the local buckling behavior and design of built-up square hollow section (SHS) stub columns made of stainless-clad (SC) bimetallic steel through experimental and numerical investigations. The study includes testing and analysis of seven stub column specimens fabricated from hot-rolling bonded SC bimetallic steel plates. Accurate measurements of dimensions and geometrical imperfections were conducted using a non-contact 3D laser scanner, and the data was processed to provide a more accurate analysis. Finite-element (FE) models were developed and validated using the scanned data, and comprehensive parametric studies were carried out to evaluate the applicability of current design methods. Proposed design methods, including a normalized slenderness limit and an effective width formula, showed improved efficiency and consistency and can be used in the future application of SC bimetallic steel structures.

Summary: This article investigates the effect of a slender web on the local buckling and post-buckling behavior of hybrid I-sections under compression. Experimental and numerical analyses show that the unbuckled portion of the slender web plate provides post-buckling strength for the I-section stub columns. Comparing existing design methods, the Eurocode 3 provides more accurate predictions than the North American, Australian, and Chinese codes, as well as the existing direct strength and continuous strength methods.

Summary: This research experimentally and numerically investigates the influences of corrosion on the buckling behaviour and bearing capacity of circular section steel tubular (CST) stub columns subjected to axial compression. A novel method considering the natural morphology of surface corrosion is proposed and verified. The study also reveals that the rough surface of corroded specimens leads to non-uniform stress distribution and changes in the buckling mode. The proposed design formula can accurately predict the axial compression strength of rusty stub columns.

Summary: This study conducted incremental dynamic analyses to investigate the relationship between the seismic performance and deformation capacity of weak-beam-type steel moment-resisting frames (MRFs) with square hollow section (SHS) columns. The analytical results obtained a relationship between the required strength of the weak-beam-type steel MRFs and the width-to-thickness ratio of the SHS columns, and evaluated the safety margin of MRFs up to collapse in relation to the width-to-thickness ratio of the SHS column.

Summary: This paper presents a comprehensive experimental investigation into the structural behaviour of high strength steel hexagonal hollow sections stub columns under concentric compression. It compares and assesses the existing design codes for the cross-sectional strength predictions of HSS HexHS. The study found that the current design codes underestimate the resistance of HSS HexHS and the Continuous Strength Method provides more accurate predictions compared to the Direct Strength Method.

Summary: The Continuous Strength Method (CSM) is a deformation based design approach that provides accurate crosssection resistance predictions by considering the interaction between cross-section elements, plasticity spread, and strain hardening. It can be used with advanced analysis for design and improves the accuracy of beam-column capacity predictions for stainless steel members.

Summary: This paper presents a comprehensive study on the material properties and behavior of Q690 high strength steel welded T-sections. Experimental tests and numerical models were used to evaluate the cross-section slenderness limits and local buckling design provisions in different design codes. The results indicate that the current limits are generally accurate and safe, with EN 1993-1-12 and ANSI/AISC 360-16 providing more precise predictions compared to AS 4100, DSM, and CSM.

Summary: In traditional end plate column splices, bolts are symmetrically placed on the four sides of square hollow sections. However, when the end plate is flushed on one or two sides for the column along the facade or at the corner of a building, the traditional analytical solution is not valid. This paper investigates the tensile behavior of asymmetric column splices using experimental, finite element, and component method approaches.

Summary: Research results show that using different types of inner stiffeners can improve the punching shear resistance of the HSSC wall in TSOB-EC connection, preventing TSOB pulling-out failure and enhancing the deformation capacity of TSOBEC. The type of stiffener has an impact on the yield bending moment and peak bending moment of TSOBEC.

Extensive parametric studies are conducted using nonlinear shell finite element models to generate benchmark structural performance data. The results demonstrate that the proposed new design rules provide more accurate, safe, and reliable predictions of the flexural buckling resistance for stainless steel hollow section columns at elevated temperatures.

Summary: The compression performance of cold-formed steel battened columns was investigated through experimental and numerical methods. Built-up sections composed of stiffened chord components and batten plates were assembled using self-tapping screws. Experimental tests were conducted on 20 simply supported columns, and the results were used to calibrate a finite element model. Parametric studies were also carried out to explore the effects of member slenderness and batten spacing on the compressive strength. The findings suggest that current design rules for cold-formed steel battened compression members need modification to ensure accurate strength predictions.
