Anti-overturning measure and construction method of foundation seismic isolation building

Abstract

The invention relates to an anti-overturning measure and construction method of a foundation seismic isolation building. The anti-overturning measure comprises anti-overturning buttresses and anti-overturning beams; the anti-overturning buttresses and the anti-overturning beams are symmetrically arranged along the four side faces of a seismic isolation support or symmetrically arranged on the twoside faces of a seismic isolation support or asymmetrically arranged on one side face or arranged on an L shape on two vertical faces; the anti-overturning beams are located above the seismic isolation support, the anti-overturning buttresses are arranged under the middle of the overhang length direction of the anti-overturning beams, the anti-overturning buttresses are poured with concrete, rubber pieces are attached to the upper surfaces of the anti-overturning buttresses, and square steel tube bottom plates forming the anti-overturning beams and pre-buried steel plates of upper seismic isolation buttresses are integrally machined. The width of the anti-overturning beams are linearly narrowed in the overhang length direction, end sealing plates are welded to the two ends of each square steel tube, and concrete is reserved on square steel tube top plates to pour vibrating seams. The anti-overturning measure is very low in cost, easy to construct, stable and reliable in performance andcapable of effectively solving the overturning problem of the foundation seismic isolation building.

Description

technical field [0001] The invention relates to an anti-overturning measure and a construction method for a basic earthquake-isolated building, and belongs to the technical field of anti-seismic engineering. Background technique [0002] Earthquake is one of the natural disasters that poses a huge threat to human beings in the world. In order to prevent the great loss of human life and property caused by earthquakes, people are actively engaged in the research of earthquake prediction and structural engineering for earthquake prevention and disaster reduction. Because the causes of earthquakes are very complicated, people's understanding of the earth itself is not enough, so it is still impossible to accurately predict earthquakes. Therefore, building earthquake disaster mitigation has become a research hotspot in this field. Base isolation is one of the better anti-seismic measures. It is different from the so-called rigid anti-seismic vibration through the seismic strengt...

AI Technical Summary

Problems solved by technology

[0004] In view of the poor tensile performance of the base isolation support 4 at the bottom of the base isolation building, after the base isolation technology is adopted for high-rise and super high-rise buildings with large height-to-width ratios, when encountering rare earthquakes, the isolation support 4 may be damaged. To solve the problem of overturning and collapsing when the tensile stress exceeds its tensile limit, the present invention provides an anti-overturning measure and construction method for a base-isolated building
