KINEMATIC SUPPORT FOR SEISMIC STABLE BUILDINGS AND STRUCTURES Russian patent published in 2005 - IPC

FIELD: construction, particularly to construct buildings and structures in earthquake zones or special-purpose objects.

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.

EFFECT: increased efficiency, strength and stability of the support under broad earthquake frequency spectrum.
