Description

A structural treatment method for vertical isolation joints of seismic isolation structures

technical field

The invention relates to a structural treatment method for vertical isolation joints of an earthquake-isolation structure, belonging to the technical field of building isolation.

Background technique

Earthquake is a very serious natural disaster. During the earthquake, the surface buildings will be distorted and deformed. When the earthquake is relatively strong, they may even collapse, causing huge economic losses and casualties.

In order to ensure that buildings and bridges play their due functions in earthquakes and reduce earthquake disasters, as an effective structural shock-absorbing control technology, seismic isolation technology has received extensive attention from engineering and academic circles, and has been widely used in buildings and bridges at home and abroad. It has been widely used in earthquake resistance and other engineering results.

At present, the seismic isolation design software and design methods of buildings and bridges are relatively mature, but the seismic isolation structure has always been a problem that plagues the designers of buildings, structures, and equipment. Relevant studies have shown that if the seismic isolation structure is not properly handled, the seismic isolation effect will be greatly reduced, and it will even be counterproductive, making the structure in a more dangerous situation.

The handling of vertical separation joints often causes headaches for designers, especially when there are functional connections between buildings on both sides of the vertical separation joint. The traditional simple solution is to directly lay overlapping steel plates on the isolation joints, and then directly make a decoration layer on them. This method can meet the daily traffic function, but it cannot meet the waterproof requirements, especially when an earthquake occurs, because the rigidity and strength of the steel plate plane are huge, which hinders the relative movement of the structures on both sides of the isolation joint, causing damage to the structures on both sides, and the decoration debris and All steel plates are in danger of falling, posing a threat to personal safety. At present, there are few similar products in the market, which can only deal with narrow vertical isolation joints, and the price is high, which cannot meet the requirements of wider vertical isolation joints in seismic isolation buildings.
