description: The given work is devoted to study behavior of T joints under out-of-plane bending. The research set the following goals:
1. Theoretical calculation of joints resistance;
2. Finite element analysis;
3. Comparison of the results of theoretical and numerical calculations;
4. Discussion on the relevance of the reduction coefficients;
5. Investigation of the improving effect of fillet welds on the structural properties of tubular joints.
The research was carried out using finite element analysis. The validation with the existing experimental results was conducted. As a result of numerical calculations resistance and stiffness of investigated joints were determined. The comparison of theoretical and numerical results was conducted to assess the reliability of theoretical results. The thesis also discovers the improving effect of fillet welds on the structural properties of tubular joints.
Comparison of the results, obtained through FE analysis and using design rules, shown that methods of EN 1993-1-8:2005 give reliable results even without reduction coefficients. Failure modes of investigated T joints depend on value Î² and turned out to be similar to the failure modes in EN 1993-1-8:2005. The conducted research revealed that fillet welds have an improving effect on resistance and stiffness of T joints. This fact should be taken into account to avoid overly conservative result. Thus, the results of the research can help to make a step forward in developing a sustainable and consistent approach for the design of tubular joints, including their resistance and initial stiffness.
