Behavior of reinforced concrete columns strengthened with hybrid NSM-CFRP strips and CFRP wraps under axial compression and biaxial bending

Key Points

• Columns showed enhanced performance under biaxial bending with hybrid NSM-CFRP strips.
• The maximum axial load capacity was increased by 25% across tested columns.
• Observation focused on reinforcing techniques that integrate CFRP wraps for improved outcomes.
• The findings highlight the potential for using advanced materials in structural applications.
