摘要：

The paper is a presentation of experimental model studies on thin-walled cylindrical structures containing large cut-outs subject to torsional deflection. The effect of rigidity of the frame reinforcing a cut-out on form and magnitude of post-buckling deformations occurring in operation conditions is analysed. A methodology based on numerical tools is proposed for determining alternative solutions in the design of structure skeleton leading to improvement of operation stability.
