EARTHQUAKE-RESISTANT BUILDING STRUCTURE Russian patent published in 2016 - IPC E04B1/84 E04H9/02 

FIELD: acoustics.

SUBSTANCE: invention relates to industrial acoustics. Earthquake resistant building structure, comprising a frame building with foundation in basement with vibration insulation system, bearing walls with enclosures in form of floor and ceiling, which are lined with sound-absorbing structures, window and door openings, as well as custom-made absorbers containing frame in which sound-absorbing material, and arranged over noisy equipment, base bearing floor slabs have at their attachment to carrying building walls damping system consisting of horizontal vibration isolators, accepting vertical static and dynamic loads, as well as vertical vibration isolators accepting horizontal static and dynamic loads, sound-absorbing structure of building is made as a multilayer sound-absorbing element made in form of five layers, two of which, adjacent to walls are sound-absorbing layers from materials of different density, while three central layers are combined, and axial layer is sound-absorbing while two symmetrical adjoining layers are made from sound reflecting material from complex profile composed of evenly distributed hollow tetrahedrons, which enable to reflect sound waves incident in all directions.

EFFECT: technical result is increasing efficiency of seismic stability of buildings.
