Analysis of different approaches to the calculation and design of road structures from corrugated metal

ntroduction. In order to improve the design methodology, particularly in the calculation of transport construction objects made of metal corrugated structures (MCS) with increased hole size (small bridges and arch-shaped overpasses, drainage pipes under road embankments), which are still relatively new in our country, it is important to have a better understanding of the features of different approaches to calculation and their impact on the results. Problem Statement. The current regulatory and methodological documents in our country concerning the design of road structures made of corrugated metal [1] include a methodology for analytical calculation of such structures only in the form of round pipes with a diameter of up to 6 meters and it requires improvement, while structures of other shapes and sizes are recommended to be calculated using the finite element method (FEM). It is advisable to improve and supplement the existing normative analytical methodology for calculating structures made of corrugated metal with a better understanding of the characteristics of existing approaches.
