“…17(a)-(c). The deformation of the RHS X-joints using the same steel depends on the joint axial stiffness which increases with increasing β ratio and with decreasing 2γ ratio [34]. The RHS X-joints with larger β ratio and lower 2γ ratio have larger joint stiffness and could be subjected to larger brace loadings and thus higher stresses before the violation of the indentation limit.…”

“…Liu et al [26] proposed a general form of CSFs, which seems controversial due to the differences of boundary conditions and joint dimensions. The analysis by Garifullin et al [27] indicated that the existing CSFs for resistance are inapplicable for initial stiffness, and thus proposed new functions for initial stiffness. Similarly, the applicability of the existing CSFs for reinforced joints is also unclear.…”

The collar plate (CP) is applicable for the reinforcement of both new designed and in-service joints, yet the design approach for the reinforcement requires further investigation. The current paper investigates the effect of various geometrical parameters as well as chord stress ratios on the compressive capacity of the collar plate reinforced (CPR) square hollow section (SHS) T-joints. The finite element (FE) models of the CPR SHS T-joints are built and validated using experimental data. Extensive parametric studies are carried out to evaluate the influence of parameters such as the brace to chord width ratio, the width/length and thickness of the CP, as well as the chord stress ratio. The brace to chord width ratio and the CP thickness are identified as the key parameters, and three typical failure modes are observed. Finally, bearing mechanism of CPR T-joints is discussed and design equations are proposed based on the failure modes. The failure-mode-based equations agree well with both parametric data and orthogonal analysis results, which provides reference for the practicing engineers.

“…The influence of chord axial stresses on the behaviour of joints was investigated in [10]. The behaviour of RHS T joints with initial imperfections was investigated in [11,12]. Currently, the equations of Wardenier are employed in many design standards, including EN 1993-1-8:2005 [13] and CIDECT Design Guide [14].…”

Resistance is the main property of tubular joints. The determination of the joint resistance from the experimental load-deformation curve always represents a challenging task. Currently there are two main methods to find the experimental resistance, which are called plastic and ultimate resistance. However, there is no single opinion on which one should be commonly used. Based on the experimental results, this paper directly compares the two existed approaches. The study is restricted to welded square hollow section T joints under in-plane bending moment. The paper considers only the joints with β < 0.85, i.e. when the behaviour of the joint is governed by chord face failure. The results show that plastic resistance leads to more conservative results than ultimate resistance, providing thus safer results. However, attention should be also paid to the difference between the labour intensity of the presented methods.
