BG105408A - Antiseismic building structire and antiseismic support - Google Patents

Abstract

The structure and the support find application in the construction of building in seismic areas. Independent relation in the forces in the construction resulting from the difference in the deformations, conveyed by individual support is achieved. The support enables the absorption of the forces acting on the building from the state of rest to intensive seismicity. The structure includes only one seismic support (1), fitted centrally in the building, and building part (3) comprising at least one floor structure (4) made of sector elements (5), arranged next to each other in the form of a circle. A central rigid ring (6) is formed, fixed to the antiseismic support (1), the sector elements (5) are engaged by a peripheral belt in the form of a steel flexible element (7), the ends of which are connected by means of a screw-type tightening connection (9). The support includes an upper (25) and a lower (26) support block, between which at least three damping stands (27) are fitted, the ends of which are fixed to the supporting blocks. The upper support block (25) is in the form of a cylinder (28) to which a building part (3) is fixed, and the lower support block (26) - to a concrete foundation (31) on which a pylon is fixed. The damping stands (27) are fitted between the upper end of pylon and cover (29) of cylinder (28). 25 claims, 15 figures
