Review of fatigue assessment approaches for tubular joints in CFST trusses

Specimen testing of concrete-filled steel-tube (CFST) joints and the fatigue assessment approaches for such joints were investigated and summarized to understand comprehensively the fatigue behavior of CFST trusses. The main factors that influence the fatigue resistance of CFST joints were discussed. Nominal stress- and hot-spot stress (HSS)-based methods were compared based on available experimental results, and the current state and...
