Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 4,   Pages 461-477 doi: 10.1007/s11709-022-0818-0

Abstract: Currently, no DoB parametric formula is available for concrete-filled rectangular hollow section(CFRHS) K-joints, despite their wide use in bridge engineering.Therefore, a robust finite element (FE) analysis was carried out to calculate the DoB of CFRHS K-jointsBased on the numerical results, design equations to predict DoBs for CFRHS K-joints were proposedInclusively, the CFRHS K-joints with same hot spot stresses, may have completely different fatigue lives
