Abstract

The operation of metal structures in an aggressive environment causes metal corrosion, which is typical for industrial enterprises. Incorrect operation of the load-bearing structures of the coating of the thickening housing of the Filtering and Drying Department caused the collapse of the metal truss. A verification calculation of the roof truss was performed in the LIR-STK design system of the Lira-SAPR program for design combinations of forces, as a result of which the bearing capacity of the structural elements of the trusses was not ensured. The reason for the collapse of the truss located along axis 13, A is one hundred percent corrosion of the metal caused by an aggressive environment; deviation from the project during the installation of the farm; loading with a load not provided for by the project. In connection with the identified defects and damage to the coating structures, recommendations for their restoration are proposed
