CALCULATION OF REFERENCE REACTIONS AND AXIAL STROKE OF A SECTION OF A STEEL GAS PIPELINE FOR THE OBJECT “ROOF GAS BOILER HOUSE”

The main stages of the strength calculation of a steel gas pipeline attached to the facade of a building, to determine the values of reference reactions, as well as the axial stroke of bellows compensators for the Roof gas boiler project are considered. The calculation was made on the basis of the finite element method by specialists in the Moscow city Center. Based on the results of the strength calculation, it was concluded that the strength and reliability of the considered section of the gas pipeline is ensured.

The article presents the results of research into the strength of the hatch covers of general-purpose open wagons. It was detected that strength of the standard hatch covers is not provided in operational loading diagrams. Therefore, new designs of the hatch covers for open wagons were proposed. The results of the strength calculation, implemented with the finite element method, make it possible to conclude that at basic and additional operational loading diagrams the strength values for proposed designs of hatch covers do not exceed the admissible values. The research conducted can contribute to a higher strength of the carrying structures of the bodies of general-purpose open wagons in operation, thus, guaranteeing a higher operational efficiency of the rail transport.
