ELASTIC BUCKLING BEHAVIOUR OF AEROSPACE CHS GUSSETED "T" CONNECTIONS

UDC 629.7.023:531.7:519.6 Summary 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.
