RISFatigue Performance and SCF Calculation Method of CFST K-Joints with Array-Arranged and Circular-Arranged Internal Studs
Publisher: American Society of Civil Engineers
Abstract: To reveal the mechanism by which internal studs enhance the fatigue resistance of concrete-filled steel tubular K-joints (CFST K-joints) and to develop a method for calculating the stress concentration factor (SCF) of CFST ...
Extended Formulation of Stress Concentration Factors for CFST T-Joints
Publisher: ASCE
Abstract: In previous research, the authors numerically investigated 212 finite-element (FE) models of concrete-filled steel tubular (CFST) T-joints under axial force in the brace to derive formulae for stress concentration factors ...
