Abstract:

Joint connections are widely used in the assembly of two or more structural elements. For a simple tubular K-joint, two main components are there, namely chord and bracing. Local stress in the tubular joint is extremely complex, including punching shear, shell bending, and membrane stress. It is the chord that transfers load from one brace member to another and, at the same time, sustains the severest localized shell bending stresses in the process. In this study, tubular gap K-joint under compressive and tensile loads were investigated. Case study C1 is for compressive loading acting on brace B of the model while Case study CT2 is for the compressive load on brace B and tensile load on brace A. Results shows that the highest value of Stress Concentration Factor (SCF) occurred when the brace-to-chord thickness ratio =0.6 and brace-to-chord diameter ratio, =0.9 with a magnitude of 6.1295. This is an increment of about 24% for the same loading on K-joint with =0.7.
