“…To achieve a high accuracy of the finite element solution and minimise the computational time of the analysis, the mesh size for numerical model were carefully selected. The details for mesh size sensitivity analysis were reported by Alsanat et al [29] for unfastened aluminium lipped channel sections. Similar mesh size control is employed in this study.…”

“…Additionally, aluminium alloy grade 5052 with hardening of H32, H36 and H38 [31] were also considered. The length of specimens used in the parametric study was 3d and 6d for the ETF and ITF loading conditions as recommended by Alsanat et al [29].…”

“…Investigating web crippling for aluminium members has also gained increasing attention in the last decade. Extruded aluminium sections under the web crippling action were mainly investigated [21][22][23][24][25][26][27] while limited studies were performed on roll-formed sections [28][29][30].…”

“…The finite element models were developed and analysed using nonlinear static analysis, and then used for an extensive parametric study. Alsanat et al [28,29] experimentally and numerically studied the web crippling failure of unfastened ALC sections under two-flange loading conditions (ETF and ITF). A detailed assessment of the AS/NZS 1664.1 [31], AS/NZS 4600 [32] and Eurocode 3 [33] specifications was performed and suitable modifications were made to improve their accuracy and reliability.…”

“…Based on the validation, an extensive parametric study comprising a various geometrical dimensions, bearing lengths, and aluminium alloy grades was carried out. The acquired web crippling database, in conjunction with that reported in Alsanat et al [29] for unfastened ALC sections, were subsequently used to further explore the effect of restrained flanges on the main parameters associated with web crippling. Moreover, a detailed assessment for the currently available design rules was performed, and a DSM-based approach was developed in this study to determine the web crippling capacity of fastened ALC sections under two-flange loading conditions.…”

Aluminium sections have been emerged in the industry due to the advantages such as light weight, resistance to corrosion, recyclability, and flexibility. While the construction industry is moving towards to modular construction trend, aluminium sections are considered as a vital key to achieve the desirable outputs of modular industry. Modular industry needs high performing structural elements as well as light weight elements to reduce the overall weight of the modules which directly affects the transport cost, flexibility of the modular connections, construction duration, capacity of the equipment or machineries and required numbers of construction workers for assemble. Hence, the requirement of light weight elements is evident, and the aluminium sections have been considered to replace the conventional sections. However, the structural performance of aluminium sections has to be analysed to check the appropriateness of utilization though it is reasonable. Hence, aluminium sigma sections were selected in this study to check their performance in the web crippling scenario under Interior‐Two‐Flange (ITF) loading case. Sigma sections were opted based on the merits including high torsional rigidity and resistance towards local and distortional buckling. Appropriate numerical approach was selected, and the procedure was validated with experimental results. Accordingly, comprehensive numerical investigation was carried out by including different parameters such as depth, thickness, yield, and ultimate strength and bearing length. Subsequently, the results were compared with all critical parameters and the results were provided. Suggestions and recommendations were stated to utilise the aluminium sigma sections in the industry.

SupaCee sections are addressed as one of the innovative section profiles which was introduced to the Cold‐Formed Steel (CFS) industry in the past decade. Longitudinal stiffeners and return lips are the unique features which ensured the better structural performance in terms of bending and shear for CFS sections. However, web crippling performance of CFS SupaCee section was the critical aspect to employ them in the industry as the concentrated loads could induce web crippling failures. Hence, there is a necessity to address web crippling performance of any innovative profiles to utilize them in appropriate locations. On that note, aluminum sections are now emerging in the industry as load bearing profiles considering their lightweight nature, corrosion resistance, ease of fabrication and high specific strength. Aluminium sections are considered as a replacement for CFS sections for modular constructions where the necessity of light weight is higher considering the transport costs and fabrication costs. However, web crippling performance of aluminum sections has to be analyzed to ensure the utilization in modular constructions. Hence, a superior section among available sections in terms of structural performances, aluminium SupaCee section, was considered for this study. Accordingly, a comprehensive numerical study was conducted considering various parameters such as section depth, thickness, bearing length and yield strength, after the successful validation process of the numerical models with the experimental scenarios of End‐Two‐Flange (ETF) loading condition. Ultimately, the results were compared with key parameters and suggestions and recommendations were stated for the utilization aluminum SupaCee sections in the industry.
