Axial compression failure analysis of CFST columns strengthened by UHPC encasement

Key Points

• Improved axial compression resistance was observed in CFST columns with UHPC encasement, enhancing overall strength.
• The failure analysis indicated that UHPC encasement effectively mitigates potential failure modes and increases durability.
• Assessment involved testing multiple CFST column designs with varying UHPC encasement thicknesses and configurations for optimal performance.
• These findings imply that UHPC encasement can significantly enhance the load-bearing capacity of CFST columns, highlighting its potential in construction.
