Flexural behaviour and design of cold-formed aluminium channel sections with elongated and circular web holes

Key Points

• Flexural behaviour shows significant variation when comparing sections with elongated versus circular web holes, impacting structural performance.
• Key metrics indicate that designs with elongated web holes maintain greater structural integrity, with a focus on load distribution.
• Observational analysis of cold-formed aluminium channel sections demonstrates varying strength properties based on hole shape.
• These findings may guide improved design practices, emphasizing adaptability in structural applications.
