COMBINED STRUCTURAL SYSTEM OF EARTH-PROOF MULTISTOREY BUILDING

摘要

The invention relates to structural systems of multistorey buildings of higher seismic resistance.The system comprises a centropositioned bearing structure extending for the whole buildings height, a jointed frame on reinforced concrete pillars surrounding the bearing structure and flat one-piece for storey flooring panels, wherein at each storey the bearing structure is made up from a system of cages adjoining each other having closed contours of lateral sections forming a block. Each block cage is a cast, continuous structure formed from a set of cast blocks interconnected therebetween forming a multistage closed cast structure extending for the building height.A cast block is formed by flooring panels and cast walls common for adjacent cages thus forming a closed structure.Butts of cast block walls are embodied as connecting elements reinforced by vertical reinforcement rods extending for the building height.Flexural-torsional stiffness of the structural system is enhanced.
