High-rise buildings use different structural designs, consisting of vertical elements (columns, walls, nuclei, diaphragms etc.) and horizontal elements (floors, beams, slanting belts etc.). Horizontal load-bearing structures of high-rise buildings, are, as a rule, of the same type and represent a rigid reinforced concrete disk (monolithic, precast-monolithic, precast). Horizontal structures carry vertical and horizontal loads and transmit them to load-bearing structures and foundations. To reduce wind effect, aerodynamically efficient cylindrical, pyramidal or prismatic shape of the building is chosen. The high-rise buildings designs have their own specificity, which greatly influences the three-dimensional planning and architectural and design decisions. These features include: significant loads on load-bearing structures; unequal loads on structural elements; high wind load as a horizontal component; problems of joint work of load-bearing structures made of steel and concrete; impact of natural factors (seismic, atmospheric, aerodynamic); influence of technogenic factors (vibrations, noise, accidents, fires, sabotage acts, local destruction); heightened requirements for fire safety and environment control systems; complex engineering and technical support.</p> ER -
