Abstract

The main dependences that make it possible to determine and evaluate the dynamic components of stresses and displacements in main gas pipelines under the action of a moving concentrated force are considered. The solution of the problem is given for single-span, two-span, and three-span beam transitions. According to the requirements of industry documents, decisions were made on the further operation of crossings or the need for their reconstruction.
