The widespread use of one-storey frame buildings and the absence of a normative document reflecting the specifics of designing precast concrete structures of these buildings necessitated the development of provisions for the design of the frame, as well as its individual structural elements such as foundations, foundation beams, columns, roof trusses, roof beams , slabs, crane girders and external enclosing structures. These provisions are reflected in the Code of rules 355.1325800.2017 "Frame constructions, prefabricated reinforced concrete, of one-storey industrial buildings. Design rules». The Code of rules developed by the authors' team of JSC TsNIIPromzdaniy consists of 7 sections and 4 annexes. There is a classification of buildings by space-planning solutions, equipment lifting and transport equipment, type of lighting, air exchange system and the presence of heating systems. The requirements of the Code of rules apply to the design of precast reinforced concrete frames of single-storey industrial buildings of mass use for all natural and climatic zones of the Russian Federation, except for sites with seismicity of 7 or more points and zones with permafrost. The considered document is intended for designers, developers of software systems, teachers, etc.
