Introduction As a kind of materials used widely in construction, concrete represents the character of multiphase heterogeneity in microcosmic level.
As one of the qusibrittle materials, concrete’s stress-strain curve shows the brittleness clearly.

For each strength level, the SCC and HPC mixtures were proportioned with the same water-to-cementitious materials ratio (w/cm) and binder type.
For the successful design of SCC for precast, prestressed applications, it is important to understand the material properties and mix design parameters that can influence the visco-elastic properties [5,6].

In order to reduce weight, the aviation industry uses lightweight and high-strength aluminum materials, and structures such as aircraft wing frames are machined into a grid girder structure[1-4].
The material used in the analysis was Al7075-T7451, which is the same material used for the actual Structure.

Mathematical Simulation Analysis of Concrete Perforated Bricks with Three-dimension Conjugate Heat Transfer Hong-bo XIE 1,2,3,a, Wei-bin MA 1,2,b 1.Key Laboratory of Renewable Energy and Gas Hydrate, Guangzhou Institute of Energy Conversion，Chinese Academy of Sciences, Guangzhou 510640，China； 2.Graduate University of the Chinese Academy of Sciences，Beijing 100039，China； 3.GuangDong Building Material Research Institute，Guangzhou 510160，China； aemali:gdbuilding@163.com, bemail: mawb@ms.giec.ac.cn Keywords: conjugate heat transfer; air interlayer; effective conductivity Abstract: 3-D heat transfer behaviors in two types of concrete perforated bricks used in external walls were numerically simulated.
For examples, the perforated bricks or insulation materials are usually used in external walls and double-layer low-E glasses are gradually used as windows.
Air has low conductivity than many solid materials, so that air interlayer is often used as insulation to lower heat flux through solid.

With respect to fire prevention, the selection of building materials has strict rules according to the fire prevention norm.
Due to the building function and service condition, the building materials should be flame-retarded, nonflammable or self-extinguishing, or materials that could not release toxic gases to harm people in case of fire.
