Seismic isolation is an important and effective method for rehabilitating buildings and roads to resist earthquakes. There are different types of seismic dampers according to their design and specifications. Seismic dampers do not prevent or stop earthquakes but soften their intensity by absorbing and dispersing earthquake energy to reduce distortions and deviations in buildings. Seismic dampers can be divided into three types: compression dampers that rely on compressible materials inside cylinders; friction dampers that operate between connecting elements; and flexible dampers that rely on compliant linking elements. The paper provides illustrations to further explain how these damper types absorb and disperse energy.

2. The seismic isolation from one Important and effective in the rehabilitation
of buildings, roads For earthquake resistance and strengthen
Damper seismic type differs-
According to its type and specifications to the scene of a signed
In origin and it does not prevent or stopping quake
It softens the intensity and absorption
And dispersing the earthquake energy to reduce distortions
Deviations in the building to become
Acceptable and within the permissible according to the codes
-Can be divided into types of dampers and method
Dispersing the quake according to:
Dampers rely on compression material-1
Sticky inside the cylinder
Friction dampers operate between the elements of the link-2
Dampers rely on flexible and compliant element-3
Link between the elements
And an increase in the illustration and explanation of these types of
Dampers and how they work in the absorption
And dispersing the energy and that access to the paper
