Analysis of the influence of the structural form and material of steel tubular chief beams on the service life of the composite small bridge superstructure
The paper analyzes the physical and mechanical properties of steel pipe materials and compares the steel of different brands in accordance with the requirements of the normative and technical documentation for bridge structures. The influence of the structural form of the cross section of the bridge members on the resistance to atmospheric corrosion during operation is estimated. Recommendations on the use of oil and gas industry pipes in the small bridge superstructure are given.
