What is the meaning of "double walls" or "double columns" made on both sides of the seam when doing earthquake proof joints?
The foundation is one, the upper wall or the pillar is juxtaposed, there is a small gap in the middle, and there is a buffer in the earthquake.
The shock resistant joint can be used to segment complex structures into regular structural units, which can reduce the torsion of houses and improve the seismic performance of structures. But the earthquake damage shows that the width of the seismic joint determined according to the standard requires the possibility of collision in the case of strong earthquake, and the excessive width of the seismic joint will bring difficulties to the design of the building facade. Therefore, it is a difficult choice to design shockproof joints for structural design.
Shock proof joint refers to the design of a building in an earthquake zone. In order to prevent the earthquake from damaging the building, the shock proof joint is used to divide the building into separate parts with simple shape and uniform structural rigidity. A gap set in advance to mitigate or prevent collisions between adjacent structural units caused by earthquakes.
