Axial compression behavior of square concrete-filled steel tube columns with stiffeners and multi-spiral stirrups

Key Points

• Improved axial compression behavior is observed with the addition of stiffeners and multi-spiral stirrups.
• The introduction of stiffeners significantly increases load-bearing capacity, enhancing column stability under pressure.
• Assessment demonstrates the effectiveness of square concrete-filled steel tube columns in construction applications.
• Findings indicate the potential for safer and more resilient building structures with these advanced column designs.
