摘要：The paper presents an innovative concept of integral stiffening of the thin-walled structures based on the use ofcurvilinear elements. The analyzed system in the form of a thin-walled spatial structure was subjected to a nonlinear numerical analysis, aimed at comparing the properties of the proposed solution with those of the referencestiffening. A comparative analysis of deformation forms and ranges as well as effective stress distributions wasconducted. The tests constituted a preliminary analysis, aimed at determining the usability of the solution, whichis the basis of the research process supported by an appropriate experiment.
