This article discusses the problem of determining the dynamicity coefficients in case of local damage to the truss in the steel frame of an industrial building. The analysis of the resistance of steel frames to local damage is an important area in the design of industrial buildings, especially those that belong to the category of increased responsibility. Damage to individual elements of the load-bearing system can cause a redistribution of forces and lead to a progressive collapse.
