ASEISMIC BUILDING Russian patent published in 2016 - IPC E04H9/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to repair, recovery or erection of aseismic buildings and structures. It is achieved by fact, that in aseismic building, containing anti-vibration foundation, horizontal and vertical bearing structures with vibration insulation system, inner partition walls, building roof, as well as door and window openings with reinforcement, basic bearing floor slabs have damping system at their attachment to bearing building walls, which consists of horizontal vibration isolators, receiving vertical static and dynamic loads, as well as vertical vibration isolators, receiving horizontal static and dynamic loads, wherein floor in rooms is made on elastic base and comprises mounting plate, made of reinforced vibration damping concrete material, which is installed on base plate of inter-floor slab with cavities through layers of vibration damping material and waterproofing material with clearance relative to bearing walls of production room, wherein cavities of base plate are filled with vibration damping material, for example foamed polymer, and each of vibration isolators consists of rigidly interconnected rubber plates: top and bottom ones, in which there are through holes arranged along surface of vibration isolator in staggered order, and form of vibration isolators is square or rectangular, and their lateral sides are made in form of curved surfaces of n-th order, providing frequency equality of vibration insulation system as a whole, wherein holes have shape providing frequency equality of vibration isolator, wherein each vibration isolator is equipped with vibration-damping inserts, arranged in holes of each vibration damper and made in form of cylindrical damping element, to ends of which flat elastic supports are rigidly connected, and inner cavity is filled with layer of vibration damping material, for example sand, density of vibration dampening layer is less than density of outer cylindrical shell of damping element.

EFFECT: reinforcement of buildings or structures, reducing their vulnerability under action of wind loads and earthquakes, improvement of seismic safety, durability and residual life.
