The article deals with the damaged metal structural elements of the out-center compressed I-pillar, corner of a single corner and others. The work of the metal element in the elastic region was experimentally studied and compared with the results of FEM calculation using ANSYS software. Good convergence of results (less than 5%) is received at calculation of stresses in a place of death of the damaged basic brace of a truss of an industrial building.
The reliability of the truss element with a defect (0.892) and without it (1.0) and the category of technical condition before and after damage are determined. Despite the fact that the voltage at the site of the defect does not exceed the maximum permissible, the category of technical condition changes from serviceable to serviceable category, and the design itself must be repaired with the elimination of damage on the support strip.
