Is steel assembly building feasible or not?

As a new modernized construction mode, steel structure assembly building has received more and more attention in the Chinese market in recent years, and its advantages and feasibility have been widely discussed.

I. What is steel structure assembly building?

Steel structure assembly building refers to the building mode that adopts factory prefabrication and on-site assembly and utilizes steel as the main bearing structure. The main feature of this building mode is that the steel structure is prefabricated in the factory and undergoes strict quality control and testing, and then the whole building is completed through transportation and on-site assembly. Compared with the traditional brick-concrete building, steel assembly building has higher strength, stiffness and stability, and is able to bear greater loads, while the construction speed is fast, the cost is low, and it has better environmental protection and sustainability.

II.The characteristics of steel structure assembly building

1. High strength and stability:

Steel structure assembled building adopts steel as the bearing structure, which has high strength and stiffness. Moreover, because steel has a certain degree of plasticity, it can maintain a relatively stable structure even under severe natural environments such as earthquakes or windstorms.

2. Fast construction speed:

Steel structure assembly building can be prefabricated in factory and assembled on site, which greatly shortens the construction cycle and time. Since there is no need to pour concrete or build walls on site, it reduces the impact on the site environment and the demand for human resources.

3. Low cost:

Steel structure assembly building adopts the way of factory prefabrication and on-site assembly, which can realize cost control in the process of production and transportation, and at the same time, it can save a lot of human and material costs in the construction process.

4. Good environmental protection:

The materials used in steel structure assembly building can be recycled, which is in line with the concept of sustainable development. In addition, as prefabricated buildings can realize energy saving and consumption reduction, steel structure assembly buildings can also save energy and reduce pollution to the environment.

III.The application scope of steel structure assembly building

The application scope of steel structure assembled building is wide, and it can be used in the fields of industrial plant, residence and commerce. In terms of industrial plant, steel structure assembly building is widely used in plant, warehouse and other fields because it has the advantages of high strength, fast construction speed and low cost. In the residential area, the features of steel structure assembled building are better reflected due to people's higher and higher requirements on the quality of life.

Meanwhile, in the commercial field, steel structure assembly building can be used in department stores, hotels, exhibition halls and other large commercial projects.

IV. Advantages and Disadvantages of Steel Structure Assembled Building

1. Advantages

(1) High strength and stability:

Steel structure assembled building adopts steel as the main bearing structure, which has high strength and stiffness and can withstand large loads.

(2) Fast construction speed:

The prefabrication and on-site assembly can greatly shorten the construction cycle and time.

(3) Low cost:

Through the way of factory prefabrication and on-site assembly, cost control can be realized, and at the same time, a lot of labor and material costs can be saved in the construction process.

(4) Good environmental protection:

The materials used in steel structure assembly building can be recycled, which is in line with the concept of sustainable development, and saves a lot of energy and reduces pollution to the environment.

2. Disadvantages

(1) Difficult design:

Since steel structure assembled building needs to consider the overall performance and safety, it is difficult to design and requires relevant technicians to have high professional knowledge and experience.

(2) Difficulty in project quality supervision:

Due to the prefabrication and on-site assembly, the construction process requires stricter quality control and supervision.

(3) Higher steel prices:

The price of steel is high, so the construction cost of steel structure assembly building is relatively high.

(4) Large coefficient of thermal expansion:

The coefficient of thermal expansion of steel is large, so it needs to be reasonably considered in the design and construction process to avoid potential safety hazards.

V. Practical application

From the practical point of view, the application of steel structure assembly building has been gradually promoted in the Chinese market. With the support of policy and market, more and more enterprises have started to get involved in this field, which has promoted the rapid development of this building model.

According to statistics, the total area of steel structure assembled buildings in China has reached 120 million square meters in 2019, up more than 50% year-on-year. At the same time, in some special scenarios, such as earthquakes, fires and other disaster environments, steel structure assembled buildings also show better seismic and fire resistance.

VI. Conclusion

To summarize, steel structure assembled building has many advantages and challenges. As an emerging industry, steel structure assembled building still needs to be improved and innovated in order to better serve people's life and development needs. In the future, with the continuous updating of policy, market and technology, it is believed that steel structure assembled building will occupy a more important position in China's construction market and become an important part of the modernized construction field.
