Abstract

The invention relates to the field of antiseismic construction and can be used for insulation and seismic protection of buildings and structures against earthquakes in seismic areas. According to the invention a device for seismic protection of buildings and structures consists of several seismic isolation supports – seismic dampers, each of which is arranged in a horizontal plane between the structure bulk and its foundation plate symmetrically with respect to the geometric center of the foundation plate and includes upper and lower bearing plates with concave working grooves turned symmetrically to each other relative to the horizontal plane and rolling body placed between thereof. The structure bulk is mounted on the upper bearing plates through the lower base plate and the lower bearing plates are rigidly fixed at the periphery of the foundation plate. The upper and lower bearing plates of each seismic damper are interconnected by adjustable damping elements. Each rolling body along its vertical axis is a barrel-shaped with horizontal upper and lower support rings. Lower horizontal support ring of each barrel-shaped rolling body rests on the corresponding horizontal support ring of the same diameter made on the lower bearing plate. Upper horizontal support ring of each barrel-shaped rolling body rests on the corresponding horizontal support ring of the same diameter made on the upper bearing plate.
