The paper presents the investigation of stability of two double-layer octahedron-based geodesic domes. The stability analysis includes the forces acting in the bars as well as the displacements of the nodes with a static point load of 10 kN applied to the top symmetrical node. The investigation was conducted with both identical constant cross-section of all the bars and variable cross-sections (with their adjustment to the internal forces) in each of the bar groups. Moreover, diagrams illustrating the rates of change of the values of the forces and displacements were presented. Also the limit values were determined, above which the analysed structures are unstable.
