Introduction With the development of industry, studies on high density and high strength materials are carried out in various fields.
Also, studies on composites are actively conducted as superior mechanical properties and high performance which could not be obtained from a single material can be obtained by combining several materials.

The materials of damping device generally were made of low-yield-point steel, Pb and rubber.
Superplastic materials have been given great attention as a new seismic damper since they have more suitable characteristics as damping materials such as low-deformation stress, no work-hardening and high ductility [2,3,4,5,6].
According to GB/T 7314-2005(in China), metallic materials-compression testing at ambient temperature, the compression specimens were prepared with gauge lengths of 12mm and 8mm diameter.

The interaction behavior between the materials concrete and steel under a state of high stresses and deformations, the slip of reinforcing steels and the concrete core containment are also important phenomena which must be considered in the modeling of RC structures beyond the yielding.
Appropriate Lagrange analysis for a reinforced concrete or Euler suitable for a rock material, uses nonlinear properties induced by the nature of material itself in the time domain thus following the evolution of the structural response.
In a fiber model, each section of the structure is divided into a number of layers or fibers and each layer is modeled by a constitutive law suitable to materials of this particular layer.

The main components of the foundry waste sand and slag generated by casting are siliceous and calcareous granular materials, which meet the needs of engineering construction materials, they have a broad application prospect.
Meanwhile, the engineering construction needs a lot of raw materials, the granular and powdered materials account for the larger proportion in it, while the composition of foundry waste sand and slag is siliceous and calcareous granular material, which is very suitable for engineering construction.
In recent years, the research of foundry waste sand as a building material is more, basically it is to be used for building materials.
In Japan and America, through a series of sieving, magnetic separation, etc, slag can be used as road base material with building materials according to certain gradation.
An overview on beneficial reuses of waste foundry sand as construction materials.

After recovery, these materials are either reused directly for low purity materials or purified before reuse or they may be disposed off.
Encapsulation in Thermo Plastic Materials In this method contaminated material is mixed with molten thermo plastic materials in special tanks to form slurry fluid upon mixing.
It cannot be used in areas with buried pipes and where there is large accumulation of flammable or explosive materials [16].
