Purpose: To investigate the potential application of cold-formed thin-walled steel sections in bridge construction. To review the existing calculation methods for thin-walled structures in national and international regulatory documents. To analyse the strength and deformation characteristics of the designed structure. To consider the possibility of adjusting the generally accepted calculation methodology and regulatory requirements. To provide substantiated evidence regarding the feasibility of using cold-formed thin-walled sections in the construction of bridges. Methods: Mathematical and finite element modelling, methods of structural mechanics, and the structural engineering design method were used. Results: The design of the bridge span structure, with the main beams made of cold-formed thin-walled steel sections, has been proposed, and the stress-strain state analysis has been performed. The calculations have demonstrated that the structure is capable of supporting pedestrian traffic loads without compromising its load-bearing capacity or rigidity. The research has shown that the current calculation method for thin-walled rods and the regulatory framework itself are both flawed. Practical significance: It is necessary to revise the requirements of regulatory documents on the design and calculation of bridge structures. The generally accepted methodology for calculating structures from coldformed thin-walled steel sections also needs to be adjusted so that it can be used for the calculation of bridge structures.
