description: The given work is devoted to the study of the influence of extreme snow impacts on the stress-strain state of metal frame structures and the development of a method for maintaining the construction height of the ceiling, taking into account the extreme values of snow loads. The tasks that were solved in the course of the study: 1. Two variants of the steel frame have been developed according to the frame and frame-braced structural scheme, their calculation has been made for the action of the loads adopted in accordance with SP 20.13330.2016. The analysis was carried out and the most preferable framework was selected. 2. The calculation of the accepted version of the frame for the action of combinations of loads, taking into account the extreme snow load, has been made. 3. A comparison was made of the stress-strain state of the frame elements under the action of climatic loads according to SP 20.13330.2016 and special climatic loads according to SP 296.1325800.2017, and the contribution of an additional coefficient of extreme snow load to the selection of sections was estimated. 4. The rationality of using steels with a yield strength of more than 375 MPa in the proposed design solution has been assessed, recommendations have been developed for the design and installation of elements and assemblies of the steel frame. The paper presents a constructive solution for a steel frame that takes extreme snow loads. When choosing a frame, special attention was paid to the selection of criteria that have the strongest impact on the technical and economic parameters. Based on the results of the calculations, the most profitable version of the steel frame was determined, and a method was proposed for maintaining the construction height of the overlap, taking into account the extreme values of snow loads.
