COMPOSITE MULTI-STORE BUILDING FRAME MADE OF REINFORCED CONCRETE Russian patent published in 2004 - IPC

FIELD: building structures, particularly concrete frames of buildings built in different areas, including seismic region. SUBSTANCE: frame includes composite or cast-in-place columns and flat composite floor discs formed by cast-in-place bearing and fastening beams made of reinforced concrete. Beams are united together with columns into closed frame cells. Composite walls of reinforced concrete are placed in groups within the bounds of frame cells. Composite walls are connected with each other by cast-in-place seams. Composite wall ends are supported by bearing beams. Continuous bearing beams in each span between columns have cross-sections with varying width. Cross-section width is changing from maximum value located near columns to minimum value in span center. Composite slabs within the bounds of each cell have different lengths. The outermost slabs positioned near fastening beams have the smallest lengths, slabs located in each cell center have the greatest lengths. EFFECT: reduced frame specific metal consumption, improved frame performance due to possibility of column grid spacing increasing. 6 cl, 13 dwg
