China is a big country in steel production and a big country in the steel structure industry, with a steel…
The large-span steel structure buildings have the advantages of high stability, environmental protection, high economic efficiency, and dramatically reduces labor costs. Its application in construction can meet the development trend of the times and promote the sustainable and healthy development of the construction industry.
Large-span steel structure buildings have apparent advantages in stability and construction performance. It has good development prospects in the future and is worthy of vigorous promotion and application.
Large-span Steel Structure Building:
In the context of the continuous advancement of the modern construction industry, large-span steel structures have been widely used.
The application has the advantages of strong load-bearing performance, good extension performance, large rigidity, and convenient construction. The application is more utilized in construction. According to the spatial structure characteristics of the large-span steel structure buildings, it is suitable for the combination of planes of different shapes. Since the application of large-span steel structures, it has played a significant role in industrial buildings, public buildings, commercial buildings, and other fields.
The characteristics of large-span steel structure building:
- The prefabricated components in the factory directly hoisted after being transported to the construction site, which significantly saves the process and dramatically improves construction efficiency.
- Industrial production carried out, and various structures integrated into the factory, ensuring the integrity and stability of the frame.
- It can meet the needs of multiple building heights and different building planes.
- It can use in conjunction with non-load-bearing lightweight wall materials, and the construction and installation are highly industrialized.
- The components are high precision, and the construction hoisting speed is fast.
Advantages of large-span steel structure buildings:
Improve the seismic resistance of buildings
The large-span steel structure buildings have good ductility. When damaged under dynamic impact load, it can absorb a lot of energy. Thereby reducing the risk of brittle damage of buildings and significantly improving the seismic resistance of structures.
The steel structure can realize factory production, and the prefabricated production components are transported to the construction site for assembly. With less on-site pollution, it meets the requirements for building green standards. And can give full play to the high-strength characteristics of steel, saving structural engineering materials.
The available resource consumption per square meter is between 800 and 1000 kg, while the resource consumption per square meter of traditional concrete buildings is more than 1800 kg. The construction and production process of steel structure is more than 30% energy-saving than the concrete structure process.
If adopted the dry construction, the water-saving rate will exceed 30%, and dust pollution will be reduced by more than 80%. When steel structure building reaches the end of its service life, the construction waste formed by the demolition is less than 25% of the traditional concrete structure, which can leave more useful resources for the development of the construction industry. The discarded steel components can also be recycled and reused. The reuse rate can reach more than 90%.
Reduce labor costs
The construction industry is facing the problem of rising labor costs, which has become the main problem restricting the sustainable development of my country’s construction industry. Large-span steel structure industrial buildings can realize industrialized prefabrication, reduce the number of personnel required for on-site construction, reduce the difficulty of human resource allocation, and save construction costs.
It can obtain more economic benefits
Large-span steel structure buildings have relatively lightweight. Compared with traditional reinforced concrete buildings, their essential cost saved by more than 30%, and the comprehensive transportation of materials is very relatively low. Coupled with the advantages of high strength and relatively small cross-sectional area of components, the construction area of industrial buildings can be increased by a range of 5% to 8%.
Besides, the steel structure can be industrialized prefabricated production, on-site assembly construction, the construction quality is guaranteed, and the intrinsic value of industrial buildings can be effectively improved. The construction speed is also relatively fast. Compared with reinforced concrete structures, the total construction period can be saved by more than 40%, which can be put into use quickly and reduce the cost of capital use.
Under the conditions of the same floor and height, the wall area is smaller, which can reduce the use of air conditioning, save energy, and reduce maintenance costs. Besides, large-span steel structure buildings have extensive windows and have better lighting and ventilation effects, which can provide a brighter and more comfortable environment for industrial production.
Large-span steel structure buildings have more prominent advantages in terms of self-weight, strength, environmental protection, economic benefits, and seismic resistance. Whether it is from the perspective of necessary materials, design, production, and construction specialization level, or the philosophy of industrialization of steel structure buildings, there is a good development trend.
