To ensure the prevention of the negative impact of such waste and ensure environmental safety, the global community adopted the following hierarchy of the waste management (by priority): maximum use of feedstock and raw materials; prevention of waste generation; reduction of formation and reduction of the hazard class in the sources of their formation; processing, disposal and neutralization.

When the thickness ratio is less than the LTR and the strength ratio is less than LSR, plastic deformation would occur in both materials.
The above equation provides the relationship of the stress state in materials A and B for the given thickness ratio.
Hence, the LTR and LSR can be obtained as (6) The LTR depends upon the tensile strength in the lesser thickness material and the yield strength in the greater thickness material while the LSR depends upon the thickness ratio of two materials [10].

Secondly, geometrical information, structural constructions and the material properties are to be investigated in details.
Investigation of Geometrical Information, Structural Constructions and Material Properties For historic buildings, the material properties are usually deteriorated to some extent, and the design approach as well as structural constructions may not meet the requirements of current design and construction codes.
The investigated mechanical properties of materials should be applied in the above analysis procedures.
The design strength of materials fd was calculated using Equation (1) (MoHURD and GAoQSIQ 2005), d df fγ= (1) where f means the investigated material strength under static load, and γd means the comprehensive adjustment factor for material strength under dynamic load.
