(54) SE SE YSM FOUNDATION OF WHOM BUILDING, CONSTRUCTION

The invention relates to construction, in particular, to structural instruments of the foundation of seismic buildings and structures. The foundation of a seismic resistant building is known, including a plate placed on the ground of the base and an optical element l installed on it through an elastic layer. The closest technical solution k. The proposed is the base of the earthquake-resistant building including a plate placed on the ground and an operatic element mounted on it. , having spherical interacting support surfaces 21. A disadvantage of the known foundations is the insufficient seismic resistance of the building and structure. The purpose of the invention is to increase the seismic resistance of buildings, structures. The goal is achieved by the fact that the foundation of an earthquake-resistant building, a structure that includes a slab placed on the ground base and a supporting element fixed to it, having spherical interacting supporting surfaces, is provided with enclosing blocks, compensators and elastic beams, and the enclosing blocks are placed on the slab parallel to the supporting member with the gap relative to its side walls, the compensators are placed in and interconnected by means of elastic beams, passed through the body of the support element, and the plate is made of curvilinear elastic layers arranged one above the other, interconnected by means of plates penetrating the elastic layers in the direction perpendicular to the bottom of the plate. In this case, the plates can be buried in the base soil. FIG. 1 shows the proposed foundation, section A-A in FIG. 2; in fig. 2 - the foundation, the plan. The foundation of the earthquake-resistant building includes the base 1 slab 2 placed on the ground and the supporting element 3 installed on the support element having spherical interacting supporting surfaces 4 and 5, blocks 6, compensators 7 and elastic beams 8, and enclosing blocks 6 are placed on top 2 parallel to the supporting element . that 3 s. gap 9 relative to its side walls iO; Commenters 7 are located in health center 9 and are interconnected by means of elastic balls with S, run through the body of the support element 3 and plate 2 is made of curvilinear elastic layers arranged one above the other, interconnected by means of plates 11, penetrating the elastic layers and in the direction, perpendicular to section 12 of plate 2. The plates 11 can be made in the form of piles and buried in the ground of the base 1, as well as in the body of the enclosing blocks 6.

In order to prevent the displacement of the supporting element 3 relative to the plate 2, an elastic core is installed as a pile 13; The supporting element 3 can be made of separate parts, rigidly joined together by welding the inserts 14.

The principle of operation of the seismic CTdtKoro foundation structure is as follows. .

Under the action of seismic shocks, the oscillations of the supporting element 3 are suppressed due to the attenuation of seismic waves propagating through several elastic layers of the plate 2, enclosing blocks 6 and compensators 7. At the same time, the elastic 8 ensures uniform load distribution on the plate 2.

The use of the foundation improves the seismic resistance of the building and the structure.
