SUBSTANCE: reinforced concrete building frame comprises columns of extreme rows and of columns of internal rows of rectangular section with relation of side not less than 1: 3. Columns are fitted with grooves which accommodate butts of collar beams of extreme and internal rows. Columns of extreme rows are installed with bigger side of section along length of building and columns of internal rows are set perpendicular to length of building. Collar beams of extreme rows enter grooves of extreme columns and have width equal to or larger than doubled thickness of column. Collar beams to support plates of floor are installed in grooves of columns beneath collar beams of internal rows by thickness of collar beam and collar beams of internal rows are provided with flanges cut along longer sides of collar beams through half of their thickness. EFFECT: reduced usage of materials and labor input thanks to more complete utilization of strength properties of fitting and concrete. 5 dwg
