Anti-seismic device of building

Abstract

The invention discloses an anti-seismic device of a building, comprising integrated right-angle anti-seismic backstraps which are arranged below a pillar in a building and are respectively fixed on the pillar and the ground, wherein the upper half part of the integrated right-angle anti-seismic backstrap fixed on the pillar is an upper backstrap, and the lower half part of the integrated right-angle anti-seismic backstrap fixed on the ground is a lower backstrap; and the corner piece of the integrated right-angle anti-seismic backstrap is an arc-shaped corner. The invention provides an anti-seismic device of a building, which has favorable anti-seismic effect on buildings, convenient installation and low manufacturing cost.

Description

technical field [0001] The invention relates to an anti-seismic device of a building. Background technique [0002] The basic types of building objects that are resistant to earthquake damage in countries all over the world are all insert-type overall structures (for the earth) that mainly absorb earthquake energy, that is, the foundation and superstructure of the building are designed as absolutely inseparable rigid bodies that are inserted into the earth. Therefore, the mechanical analysis and design of the building's resistance to earthquake destructive force has to consider the seismic performance of the building from the perspective of the overall structure. The earthquake destructive force impacts the foundation of the building through the soil layer and rock and directly transmits the impact force to the upper part. Structure, the action force (load) of the superstructure plus the internal force generated by the earthquake reacts on the foundation, so the strength des...

Therefore, it is difficult for the seismic capacity of buildings to meet the actual seismic design requirements in the plug-in overall structure. The current buildings are constructed conservatively, and a large number of steel bars and cement inserts are invested in the foundation of the building. Into the earth, the purpose is to make the building achieve better anti-seismic effect, but in the end it increases the cost of the building. Even so, in the actual earthquake disaster, the degree of damage to the building is still very serious , and then it is impossible to get rid of and reduce the earthquake disaster, causing huge losses to people's lives and property

Now, in the anti-seismic design scheme of high-rise buildings in many countries, new structures have appeared, such as the 42-storey high-rise buildings in New York, the United States, which are built on 98 rubber springs separated from the foundation. For this structure, due to The reset effect of the rubber spring is poor. When the ground shakes, the building will tilt with the deformation of the rubber spring, and under the action of the seismic wave ∽ wave, the rubber spring will also have a superimposed force, so the rubber spring It is extremely difficult for the spring to return to its original state; as another example, Japan adopts the installation of arc-shaped steel bars on the lower floors of buildings. For the structure of this arc-shaped steel bars, the amount of arc-shaped steel bars used in the implementation is too large, so it is too wasteful of materials
