Overview

Experimental investigation reveals flanged CFS-FCCWs improve ductility and energy dissipation, indicating enhanced seismic resilience.

Key Points

  • The aim is to investigate the seismic performance of CFS-FCCWs focusing on failure mechanisms and energy dissipation.
  • Experimental program with six full-scale CFS-FCCW specimens
  • Specimens subjected to quasi-static cyclic loading
  • Varying cross-sectional configurations and dry connection types
  • H-shaped configuration improved peak load by 74.8% to 316.3 kN
  • Ductility coefficient increased by 30.5% to μ = 2.56
  • Angle connection showed optimal energy dissipation capacity without premature failure
