Introduction Considerable research work in the field of material science has been progressed towards the development of new light – weight, high performance engineering materials like composites.
Metal matrix composites have become the necessary materials in various engineering applications like aerospace, marine and automobile engineering applications, because of their light-weight, high strength, stiffness and resistance to high temperature [Tomac et al., (1992)].

Secondly, materials prepared.
The form, height, color, materials, structure, etc are based on the traditional architecture for the new construction being ready; the height is controlled within 1～3 layers.

Seismic Performance of Steel Frames for Sustainable Structural System Oh, Sang Hoon1, a, Ryu, Hong Sik2,b 1 Ph.D, Professor of Dept. of Architectural Engineering, Pusan National University, Korea 2Ph.D, Senior Researcher of Research Institute of Industrial Science & Technology(RIST), Korea aosh@pusan.ac.kr, brhs@rist.re.kr Keywords: Sustainable structure, Full-scale test, Damper, Moment resistance connection, Moment frame.
The survey showed that when compared with existing materials, the environmental load of the steel structure was reduced by approximately 17% in the case of CO2 emissions and approximately 25% in the case of energy consumption.
To contribute to the global environment in the construction sector, particularly in building structures, it is necessary to use those materials and methods that reduce environmental load, i.e. less energy consumption and less waste.
It also requires a design that enhances durability that translates into extending the life of buildings; and the modularization and unitizing design where the materials from the buildings can be removed and recycled and reused, simplifying the entire building design, construction work, and maintenance.

Four commercially available elastomeric materials were selected for irradiation and testing.
The neutron/gamma dose ratio depends on the materials composition and on the spectra of the radiation fields.
All the materials showed significant radiation-induced degradation of their mechanical and structural properties.
A reduction of the swelling ratio (SR) with dose is observed for all the materials.
In fact, the total dose rate absorbed by the materials is approximately proportional to the reactor power.

Besides, there is chemical material leakage to the songhuajiang river in Jilin and acid water pollution accident in Fujian, etc.
Chemical industry is a high-risk industry, according to the above chemical accident, from the transportation and storage of production materials, production process, to the transportation and storage of Industrial products, any improper handling will cause severe disasters of city safety.
On the production of raw materials, such as Sinopec, whose raw materials are natural gas (methanol, acetylene) and oil, in, once improperly transport of goods stored, will not only cause environmental pollution, but also cause explosion and poison residents.
