The earthquake caused the collapse of a large number of houses in the local area, which made people pay attention to the earthquake resistance of the house. Traditional civil and concrete structures are prone to collapse in earthquakes. For this reason, many experts and people in the industry have called for the construction of steel structure residences with strong earthquake resistance.
The steel structure represents the future of building earthquake resistance. It is reported that the steel structure has good ductility, which can offset the energy consumption of seismic waves. In addition, the steel structure weighs less than other structures, which greatly reduces the impact of earthquake.
People in the industry call for the construction of steel structure residences not only because of their strong earthquake resistance, but also because of “energy saving and environmental protection”. Vigorously promoting the production mode of steel structure construction can fundamentally solve the current dilemma of “building waste besieged cities”. The steel structure building adopts the prefabricated construction mode, and there is only work during construction, and there is no pollution. Judging from the average construction life of 80 years of steel structure buildings, even if the main structural materials of the demolished steel structure buildings are recovered, the recovery rate is over 90%, which is 60% less than that of traditional concrete waste.
In addition, the promotion of steel structure construction has increased, which has brought about an increase in the demand for construction steel. On the one hand, it can partially resolve the chronic problem of overcapacity in steel companies. On the other hand, it can also provide an effective path for the national steel strategic reserve. The recovery rate of steel structure buildings is high. Once a large number of buildings are built, steel structure buildings have the potential to become “steel storage warehouses”.
The number of steel structure buildings marks the economic strength and economic development of a country or a region. A large number of steel structure venues, airports, stations and high-rise buildings have been built. In addition to landmark projects and venues, the construction of steel structures should be fully promoted in the residential construction system. However, at present, China’s construction market averages about 2 billion square meters of house construction each year, of which steel structures only account for about 6%. In developed countries such as the United States, steel structures account for more than 30% of residential buildings.
The development of steel structure residences is not only restricted by the level of economic development, technical level and commodity support, but also by people’s ideological resistance. The main reason is the lack of sufficient understanding of steel structure residences, thinking that the price of steel structure residences is “on the high side”. In addition, developers consider their own economic interests too much, and lack long-term thinking on industrial development.
In the eyes of industry insiders, although the cost of steel structure residences is much higher than that of traditional residences. However, because steel structure residences can save labor costs, 70% of the processes can be completed in the factory building, and the on-site manufacturing and installation speed is fast, which can save manpower, capital, and time costs for construction companies. In addition, the housing rate of steel structure residences is higher than that of traditional residences, with 5% more usable area per square meter, and ordinary people can benefit from it.
Industry insiders analyzed that with the advancement of urbanization, there will be hundreds of millions of square meters of urban residential shopping malls every year in the future, so there is no problem with steel structure residential shopping malls. The key lies in whether it has the ability to open up shopping malls, whether it has good steel structure housing products, and whether it can realize the industrialization of steel structure housing. After all, steel structure residences not only use steel structures to build houses, but also need complete sets of supporting products, such as sanitary ware, plates, etc. For this reason, the steel structure company should improve the power and technical level as soon as possible to reduce the cost. Industry authorities should also actively guide the steel structure industry to develop in a healthy and orderly direction.
