METHOD OF PROTECTION OF HIGH-RISE STRUCTURES FROM SEISMIC EFFECTS Russian patent published in 2023 - IPC E04H9/02 

FIELD: earthquake-resistant construction.

SUBSTANCE: invention can be used for seismic protection of high-rise structures from the influence of kinematic effects in the low frequency range. Method for passive protection of buildings from horizontal vibrations of the earth's crust during earthquakes includes separating the building mass from the movable supporting part of the foundation located in the earth's crust by placing a sealed volume between them filled with liquid under excess pressure sufficient to hold the weight of the building. A liquid with a high coefficient of dynamic viscosity is used as a liquid, and the sealed volume is made in form of one or more horizontal or close to horizontal gaps, separated by sealing seals into one or more separate sealed volumes located in the plane between the building mass and the movable supporting part of the foundation. The gap value exceeds the total height of the irregularities of the base plates of the foundation and the building mass forming the gap by the minimum thickness of the liquid layer providing the building mass with the required value of the effective coefficient of viscous friction sufficient to protect the building from the impact of a seismic wave.

EFFECT: providing passive seismic protection of buildings from destruction during earthquakes due to the separation of inertial masses, that is, the reliable separation of the building mass from the foundation, by installing between them a volume filled with liquid under pressure, balancing the weight of the building mass, while eliminating its indicated disadvantages.
