Abstract
The paper studies the metal frame industrial building during the reconstruction of its bar joists having imperfections in the form of non-uniform geometric deviations from the vertical position.
Purpose: The aim of this work is to calculate the allowable value of horizontal deviation of bar joists from the vertical position.
Methodology: The computational justification of using roof bar joists with regard to geometric imperfections in the reconstruction of the industrial building, is provided by modeling the stress-strain state of the metal frame in Ing + 2021, MicroFe software using the finite element model.
Research findings: The limiting value of the geometric deviation from the bar joist plane, at which their vertical position or replacement is not required, is justified by calculation.
