内容記述 |
To develop a calculation method for the axial load-carrying capacity of the tension side brace in CFST K-joints with an external stiffener, experimental studies on ten CFST K-joints and nonlinear finite element parametric analyses were conducted. The failure modes and stiffening effects of CFST K-joints with the external stiffener were revealed. The sensitivity of load-carrying capacity to stiffener plate and geometric parameters was systematically investigated. Existing formulas for CFST K-joints were verified to develop a new calculation method for the CFST K-joints with the external stiffener. The results demonstrate that the failure location of CFST K-joints shifts from the crown toe to the saddle and crown heel regions by the external stiffening. The external stiffener enhances the load-carrying capacity by 28.3–47.8 %. The load-carrying capacity shows positive correlations with the stiffener thickness factor (λ), stiffener height factor (η), wall thickness ratio (τ), and diameter-thickness ratio of the chord (γ) (with gradually decreasing slopes), a positive correlation with the angle between the chord and brace (θ) (with increasing slope), and a negative correlation with the diameter ratio (β). The existing calculation formulas for the load-carrying capacity of tensile brace in CFST K-joints demonstrated unacceptable accuracy for externally stiffened CFST K-joints, whereas the proposed formula for stiffened joints achieved a maximum deviation of 4.6 %, demonstrating superior computational accuracy. |
