Fang Hongjiang proposed steel building should firmly establish the concept of green building design: According to "zero resources and zero energy, zero emissions, zero pollution, zero site, Zero" concept, the establishment from the planning, design, construction, use to remove the entire life cycle of the building and construction of new model development, development, design and construction of a new generation to meet industrialization, standardization and industrialization of the modern steel residential building products.
Compared with the traditional way of civil construction, steel construction with a "light, faster, better and cheaper" four excellent performance. Steel weight and strength ratio is less than concrete and wood, under the same conditions, using the lightest weight steel buildings as a whole; steel to facilitate mechanized manufacturing, high accuracy, easy installation, short construction period, the project structure the highest level of industrialization of a structure; steel construction of the environmental damage is small, good seismic performance, and suitable for different climatic conditions and atmospheric environment; use of steel can save the cost of foundation, water saving, easy to control costs, while , can be used again, reducing construction waste.
He used a 3 layer 4-layer structure of the ordinary multi-storey frame building of steel construction and wood frame construction for comparison. "If the use of wooden structures, generally need 40 to 50 trees in about 10 years old wood; while the use of steel construction, with six scrapped cars just steel." Fanghong Jiang said. In recent years, in the world there have been several large destructive earthquakes, the most important advantages of steel construction - seismic performance - prominent. From China's actual situation, the promotion of steel in the post-disaster housing reconstruction to restore the local economy is not on the pulling power of a large concrete building, because the steel housing is a factory production, assembly at the construction site, you can save a lot of labor.
