The invention relates to aboutana earthquake resistant building including cross-spaced longitudinal and transverse wall panels, the latter of which is made in the form of a diaphragm stiffness with vertical sliding joints, communication of seismic protection, placed in vertical joints, slabs and flexible communication (USSR author's certificate N 767331, class E 04 H 9/02, 1980).The disadvantages of the known designs can be attributed to the complexity of the supporting part of the diaphragms with a curvilinear shape and nests in the upper part of the walls of the lower floor, as well as the creation of stress concentrations in the contact elements of the building when the transfer of loads from the walls of the upper floors through the convex end faces.The closest to the invention, the technical essence is the design of multi-storey earthquake-resistant buildings, including cross-spaced longitudinal and transverse wall panels, the latter of which is made in the form of a diaphragm with a vertical sliding joints between panels, communication of seismic protection and slabs, and panels internal longitudinal walls and the middle panel of the diaphragm are connected, and between the panels of the diaphragm stiffness is placed flat horizontal elements of the flexible links, communication of seismic protection in the form of wedges, the vertical ends of abutting panels of the diaphragm stiffness have slots for inserting dowels with a gap relative to the surfaces of the grooves, and the upper ends of the panels of the diaphragm the tabs in the holes of the horizontal elements with a gap relative to the surfaces of holes (USSR author's certificate N 1057666, class E 04 H 9/02, 1983).Well-known design provides the compensation of the horizontal and vertical displacements of the elements by choosing the gaps between them that causes the change in stiffness of the building.The disadvantages of the known designs can be attributed to the complexity of the production relations of seismic protection in the form of dowels and the need to use materials of high strength for the manufacture of building elements, which leads to increased material consumption of the building.The task of the invention is the reduction of the material by reducing the volume weight of its elements and reduction of seismic loads on the building elements.The problem is solved by the fact that in large multi-storey earthquake-resistant building, including spaced cross and made of panels PRA axis relative to the ends of the secondary panels inner wall and forming with the latest kernel hardness, separated from the rest of the walls vertical seams, and slabs, one part of which is supported on the horizontal members arranged on the upper faces of the panels of the transverse walls, the horizontal elements are made with the shape of the longitudinal edges corresponding to the shape of the ends supported on them floor slabs, and installed in floor slabs on end panels of the transverse walls with the formation of the cantilever ledge above the middle panel of the transverse walls and the gap between them and the other part of the floor slabs made of ribbed and supported by the outer ribs on the panel inner longitudinal walls, and the building is equipped beams, mounted on the upper faces of the panels of the exterior longitudinal walls with ligation of the seams with the seams of the latter and the inner wall panels and elastic strips are placed in the gaps between the guide beams and the middle panel of the transverse walls, wall panels, floor slabs, supported on horizontal elements and beams made of lightweight concrete and ribbed slabs and horizontal elements of heavy concrete.It is evident from Fig.1 shows a cross-section of a building; Fig.2 section a-a in Fig. 1; Fig.3 cross-section B-B in Fig.1; Fig.4 section b-b of Fig.1; Fig.5 type G and is made of panels 1 longitudinal and transverse wall 2, the core hardness 3, slabs 4, 5 and horizontal elements 6.The structure core 3 is formed by an inner lateral 7 and 8 longitudinal walls placed offset to the Central longitudinal axis of the building relative to the ends of the secondary 9 of the panels 10 of the inner wall 7.

After that install the ribbed plate 5, the remaining slabs beams 4 and 14, and then into the gaps 17 installing the elastic strip 18 and produce the final sealing of joints.The longitudinal panel 1, 8 and 2 cross walls, slabs beams 4 and 14 can be made of lightweight concrete, for example from cellular concrete blocks of class 2.5 3.5 collected in the panel. Items belt stiffening - ribbed plate 5 and the horizontal elements 6 are made of heavy concrete, for example, class 25.In the operation of the building is a spatial rigid system, consisting of cores of 3 uniting average cross-section of the panel 7 and the longitudinal inner panel 8 with overlapping in the form of a ribbed plate 5, and including end zones of the transverse walls 2 with 4 floors and exterior wall panels 1.Constructive design of the building provides the ability to perform its various elements on the volume weight and strength that provides the element 6 with the formation of the console tab 13 in the direction transverse to the panel 10, ensures collaboration at plots of the transverse walls 2 and kernel hardness 3, and installing ribbed plate 5 with the platform resting on the middle transverse wall 7 provides overlapping joint area 8 longitudinal and transverse walls 7 kernel hardness 3 and rebuilt the walls. This achieves the perception of horizontal efforts shift from seismic effects and uniform distribution of load on all elements of the building. This set installed in a level horizontal overlap elements 6, ribbed slabs beams 5 and 14 to form a continuous seismic belt stiffness, overlapping vertical longitudinal joints 1.8 and transverse walls 2.7 building that increases the seismic resistance design in General.Thus, in the proposed design solution is provided as effort reduction in the elements of the longitudinal and transverse walls, and the necessary stability of the entire building under seismic loads.

SUBSTANCE: multistory earthquake resistant building includes upper spatially stiff stories defined by columns, crossbars, floor panels and well panels; ground or the first floor formed of kinematical posts with rounded upper and lower edges so that posts may perform stable swinging during earthquake along groves. The grooves are formed in upper framing members created as a part of floor panel or ground floor and in lower framing members made as a part of foundation bearers. Rounded post edges have variable curvature acting as lockable and releasable links and limiting large horizontal movement along with retaining post capacity to reduce seismic forces affecting on buildings and structures during earthquake. Kinematical posts are monolithic or composed of several parts without embedded members. Horizontal cross-section of each kinematical post define star with 3, 4, 5, 6, 7, 8, 9 … n points, wherein unrestricted number n of star points create stiffening ribs.

SUBSTANCE: multistory earthquake-resistant building comprises upper spatially rigid stories built of columns, girders, floor panels, wall panels, and the first or ground floor or the first and ground floors made of ribbed walls. Wall ribs have rounded upper and lower edges and may stably swivel along grooves created in horizontal panels during earthquake, wherein said walls are arranged between the panels. Rounded wall and rib edges have varying curvature so that said curvature is used as engaging and disengaging links and limit large displacement along with retention of seismic force reduction properties of the walls. Building comprises independent ribbed walls installed on two levels and intermediate horizontal panel arranged in-between. The horizontal panel is solid or provided with orifices or is made as crossing beam system. Walls and ribs thereof have rounded edges with varying curvature, which create cylindrical rolling surfaces to increate mutual contact areas and decrease stress concentration in walls. Walls of each level may swivel only in longitudinal and transversal directions with respect to building orientation so that wall displacement vectors in upper and lower levels are transversal one to another.
EFFECT: increased seismic resistance and reliability, possibility to withstand broad frequency spectrum earthquakes, elimination of stress concentration.
