FIELD: erection of reinforced-concrete frameworks of multistory residential and public buildings. SUBSTANCE: pillars have a through aperture with a transverse ridge at the bottom, made integral with the pillar body to the height not less that 0.7 the height of the covering slabs. The ends of rigid inserts in the crossbars between the ends of multicavity slabs of adjacent spans across the stressed reinforcing bars are secured in joints between slabs. Bends of stressed reinforcing bars are located in the zones of rigid inserts. Embedded crossbars between the ends of slabs in adjacent spans are of a solid section, enlarged at the pillars while embedded crossbars in perpendicular direction are made of hollow prefabricated members. Local nonstressed reinforcing members are disposed in the zones of negative moments. EFFECT: improved design. 7 cl, 9 dwg
