For these components, the damaging effects from fire can vary extremely in relation to the nature of the materials involved and the relevant fire resistance.
The formula is here reported: d = Kr x v – Mr (1) Where: Kr are the re-construction costs; v is the depreciation coefficient; Mr is the value of residual materials.
Actually, many variables contribute to define the depreciation coefficients, as the age of the building, the materials used, the functional and techological solutions adoped, the manteinance condition and the economic context.

Integrating material science insights and advanced computational techniques, our model encompasses crucial nonlinearities, including material behavior and geometric variations.
Due to its economic availability and durability, it remained one of the preferred construction materials but at the same time its non-homogeneity posed a significant challenge when it comes to analysis and design.
Fiber models can define complete nonlinear stress-strain curves of materials, effectively representing important aspects of material nonlinearity[6].

Hybrid materials are attractive for a large range of applications from medicine and biotechnology to telecommunication systems and fuel cells.
The polymeric materials were characterized by scanning electron microscope (SEM) and IR-spectroscopy.
Nowadays, proton conductive membrane materials for fuel cells are of great interest.

Introduction Functional Gradient Materials (FGMs) are a new generation of engineered materials which first introduced by a group of Japanese scientists in 1984 [1, 2], as ultrahigh temperature resistant materials [3,4] for aircraft, apace vehicles and other engineering applications.
This advantage eliminates the interface problems of composite materials.
The former two methods are based on the uniform or laminated materials, accurate method often assume the elastic modulus of material along the beam thickness direction change with exponential law.
