The bracing system plays a very important role in the steel frame of an industrial building. The braces ensure the fixation of structures and their required effective lengths, give the frame overall spatial stability and geometric invariability. The scheme of bracing system significantly affects the behavior of the frame and the distribution of forces in its elements. The influence of the design solution of vertical bracing systems along the columns on the stress-strain state of the frame is studied in the article. It is shown that when using solid I-columns with the large web height (over 500 mm), to prevent their twisting and excessive displacements, it is necessary to fix both flanges of the columns in the longitudinal direction. That is why, the use of a single-plane vertical bracing system for the columns with the large web height is not recommended. For this, either two-plane braces can be used (allowing to reduce the twisting angle of the columns by 95%), or various options for fixing the flanges of the columns to struts or other structures (provide a reduction in the twisting angle of up to 88%).
