The Environmental Protection Market of Steel structure Building

Good performance of prefabricated steel structure building, energy saving and environmental protection accord with the concept of sustainable development.

The weight of steel structure material is light, and the flexibility is better than that of the traditional structure residence, which can reduce the weight of the structure by more than 30%. The weight of high-rise reinforced concrete buildings is about 1.5~2.0t/m2, the weight of steel structures of high-rise buildings is below 1.0t/m2, and the low weight is only 0.5t / m2. Light weight can reduce the cost of transportation and hoisting, and the steel structure has good flexibility. The transport radius is 10 times that of PC prefabricated concrete structure. The advantage of steel structure building appears.

When steel structures have excellent seismic performance, concrete buildings are prone to collapse, while the ductility of steel structures can attenuate seismic waves and reduce the damage caused by earthquakes. The flexible frame composed of steel beam and steel column can withstand earthquakes of more than 8 degrees, so it is widely used in earthquake prone countries such as Japan, and the occupation of steel structure in Japan is about 70%. According to the data after the Hanshin earthquake in Japan, the damage rate of steel structures is much lower than that of concrete structures. Sichuan Wenchuan earthquake, also a steel structure of Mianyang gymnasium was not damaged, and become the main location for the victims. The Mianyang Jiuzhou Gymnasium (steel structure) has become a resettlement site for disaster victims.

The steel structure has good environmental protection and energy saving advantages, the number of construction waste in China accounts for 30% to 40% of the total amount of waste, and the production of construction waste is up to 4 million tons per year. It is the first in the world. The structure of steel has a lot of dust and noise relative to the manual wet work. The steel structure has the characteristics of less dust, low noise and no pollution of the water source soil, and no asbestos, Non-toxic and harmless, can effectively reduce the number of building waste. The material of steel structure is basically steel, 100% can be recycled, fit the concept of sustainable development. In addition, the construction process of steel structure is low energy consumption, heat insulation performance is superior, and the carbon emission of residential buildings is 740. The carbon emission of the building materials per square meter of steel structure is 480 kilograms. The annual new residential area in China is about 2 billion square meters. If the steel structure buildings in the United States and other countries have reached the level of 50%, the carbon emissions can be reduced by 2.6 million tons each year. The carbon emissions are calculated according to the current 15-50 yuan / ton carbon emissions trading price in each of the cities of China. Yi right value is about 40-130 billion yuan. At present, China's steel structure accounts for about 5% of the total construction area, and the development space is huge.
