Axial behaviour and confinement-based design of short circular stainless steel tube-confined concrete columns for composite modular buildings

Key Points

• The axial behaviour of short circular concrete columns improves when confined with stainless steel tubes, enhancing structural efficiency.
• Increased confinement leads to a 25% higher load-bearing capacity in these columns, crucial for modular designs.
• Assessment of short circular columns shows significant performance differences influenced by tube confinement methods.
• Further exploration may enable design guidelines that optimize the axial performance of confined columns in real-world settings.
