Elastic Buckling Behaviour of Aerospace CHS Gusseted “T” Connections

Sa？etak Lightweight tubular structures are widely used in aerospace structures. Lattice beams are simple or gusset reinforced connections. As the gusset design offers a lot of solutions in aerospace, this paper focuses on the assessment of the elastic buckling of the most frequently used welded gussets of “T” connections. A FEM method was validated by analytic equations of a triangular gusset, and based on the results, conclusions and design recommendations are made
