title = "Experimental investigation on stress concentration factors for diamond bird beak T-joints",
abstract = "For need of fatigue assessment, the behavior of hot spot stresses of diamond bird beak T-joints in SHS trusses were investigated experimentally under axial force and in-plane bending on the brace respectively. Seven specimens of T-joints were designed with different values of nondimensional geometric parameters β, 2γ and τ. The hot spot Stress Concentration Factor (SCF) distribution and the effects of β, 2γ and τ were presented and compared to the conventional SHS T-joints. It is concluded that the SCF in the chord is higher than that in the brace under axial tension, but the situation is reversed under in-plane bending. Both the crown and the saddle are all the possible positions where maximum SCF occurs under axial force. The diamond bird beak T-joints have much lower SCFs than the conventional SHS T-joints, and thus are expected to have better fatigue strength or larger fatigue life.",
