The solution of a single-storey industrial building, of working with significant horizontal seismic vibrations. Earthquake building carried out by separating the sole-plate foundation resting on the ground, from the rest of the multi-stage foundation for the frame column. The gap formed by constructive in the individual cells are arranged point-balls bearings, have freedom of movement in the horizontal plane. Under horizontal vibrations of the earth and the sole-plate the rest of the basement and the building itself remain at rest. It noted an interesting fact: the performance and reliability of the proposed solutions of seismic stability of buildings received unexpected confirmation,  that one of the buildings in the Chilean capital of Santiago, built in the sixteenth century, survived dozens of earthquakes, is the oldest building and it became clear that its ancient walls are mounted on ball-shaped stones.

The article represents the developed construction of antiseismic bridge, designed for operating in terms of considerable longitudinal and transverse horizontal seismic vibrations. The article also gives the results of the laboratory tests of such a bridge.

The antiseismic effect is achieved due to point contacts in the form of metal balls between span and mainstay of the bridge. These balls are free to move in horizontal plane since they are located in separate coaxial metal bowls of the span and bowls of the mainstay. These balls form the required construction gap between the span and the mainstay. The diameter of the bowls should exceed the magnitude of the seismic movements potential for this area. The laboratory tests of the bridge sample revealed that during the various rates imitation and horizonral vibrations’ accelerations they do not affect the bridge span. That means the bridge span stays still without any deformations or cavings during the free moving of the interim and coastal mainstays.

The proposed construction can be used during either new constructions or existing bridges reconstruction.

A new method of leaning the building object on the subgrade is represented via a platform consisting of two ferroconcrete plates. Metal balls are placed between them to create a gap for free moving of the lower plate comparatively to the upper plate – the building base. As a result of such a leaning the effect of the most destructive horizontal seismic oscillations can be totally annulled.
