Abstract: FIELD: construction. 
     SUBSTANCE: seismic-resistant building containing the vibration-insulated foundation, the horizontal and vertical load-bearing structures with the vibration isolation system, the internal partitions, the building roof, as well as the door and window openings with reinforcement; the base bearing floor slabs in the points of their attachment to the bearing walls of the building are equipped with the spatial vibration isolation system consisting of horizontally arranged vibration isolators and vertically arranged vibration isolators. The brick wall panel is made seismic-resistant, comprising brickwork made of bricks with openings in the middle of the width and a quarter of the length from the brick butts laid on mortar with alignment of the openings into channels, and reinforcing rods passed through the channels with their rigid fixation to the butts by means of flat stops by thickness equal to the mortar joint thickness, and in the channels at the panel butts there are layers of a U-shaped type of a vibration damping material, perceiving the spatial vibration. The reinforcing bars are made damping, of two possible implementation versions. The vibration damping material layers of the U-shaped type are made out of ground worn-out automobile tires, using rubber glue, liquid glass or polymer binder as a binding agent, and rigid stops are welded after each 8÷10 rows of bricks laid on the mortar, and dampening rods are elongated using welding. In the channels of the middle zone, mortar with vibro-damping crumbs from ground automobile tires to form more rigid areas is poured. Each of the vibration isolators is made in the form of a washer mesh containing a base, a resilient mesh element and washers interacting with bushings, the base is made in form of a plate with the mounting openings, a mesh resilient element, resting with its bottom part on the base and fixed with a bottom washer rigidly connected with the base, and by its upper part fixed with an upper pressure washer rigidly connected to a centrally arranged piston covered with a gap by a coaxially arranged sleeve rigidly connected to the base, and an elastomer, for example from polyurethane, is arranged between the lower piston butt and the sleeve bottom; in the cavities of the base plate, vibration damping inserts made in the form of a cylindrical damping element are placed, the inner cavity of which is filled with a vibration damping material, and to the ends of which flat elastic stops are rigidly attached, the diameter of which is 5÷10% less than the diameter of the base plate cavities, and the length of the cylindrical damping element is 5÷10% less than the length of the base plate cavities. After installing the vibration damping insert, the resilient stops are sealed with a foamed polymer flush with the butt faces of the base plate. 
     EFFECT: strengthening the construction of buildings or structures, reducing their vulnerability when exposed to wind loads and earthquakes, improving their seismic safety, durability and residual life.
