Analysis of light steel structure technology
Analysis of light steel structure technology:
a full-dimensional analysis from material properties to seismic performance
In the field of construction, light steel structure technology is emerging with its unique advantages and has become a new trend in the development of modern construction. This article will conduct a full-dimensional analysis of light steel structure technology from material properties to seismic performance.
Material properties: lightweight and high-strength foundation
Light steel structures mainly use hot-rolled light H-steel, light welded steel, high-frequency welded steel, cold-bent thin-walled steel, thin steel plates and thin-walled steel pipes. These materials have the remarkable characteristics of light weight and high strength.
Take light steel as an example. Under the same span and load, the weight of ordinary steel roof trusses is only 1/3 - 1/4 of the reinforced concrete roof trusses with the same span. If thin-walled steel roof trusses are used, it is even lighter, only 1/10. Steel has a uniform texture, isotropy, a large elastic modulus, good plasticity and toughness, and will undergo a large plastic deformation process before destruction, which can absorb and consume a lot of energy.
Industrialization and environmental protection advantages: a combination of high efficiency and green
Light steel structure has a high degree of industrialization. It is composed of various profiles and steel plates. It is machined and manufactured in a professional steel structure factory. It is then installed on site by professional construction personnel. It can greatly shorten the construction period, reduce the cost, and improve economic benefits. At the same time, light steel structure has good environmental performance. The use of light steel structure can greatly reduce the amount of sand, stone, and ash. The use of 1t steel structure can reduce the amount of concrete by 7t, reduce the waste of non-renewable resources, and conform to the development concept of green buildings.
Seismic performance: excellent safety guarantee
Light steel structure performs well in earthquake resistance. Steel structure has good ductility, good earthquake resistance and wind resistance, and light damage. Data from the earthquake laboratory show that the earthquake resistance of light steel structure houses is 2-3 times that of traditional brick and wood houses. When the brick and wood structure house collapses, the light steel structure house only undergoes recoverable bending, and because steel is easy to process, it is easy to repair after the disaster.
The components of the light steel keel structure building form a "skin effect" with the exterior wall panels, and the ability to resist horizontal and vertical loads is greatly improved. The main body of the house is assembled with bolts to form a whole, which is closely connected to the foundation and can withstand earthquakes up to 9 degrees.
Application range: wide and flexible
The application range of light steel structure is very wide. It was originally mainly used for buildings with small loads and small spans, such as small warehouses and simple factories. With the development of technology, its application range has been greatly expanded, and it is now widely used in warehouses, offices, industrial plants, sports facilities and other building types.
For example, Shijiazhuang Eiffel Steel Structure Co., Ltd., as a professional company integrating design, production, sales and service, is committed to the research and development and innovation of various new energy-saving and environmentally friendly houses and construction methods, focusing on the design and production of light steel structure houses and container houses. The company's main products include multi-story light steel buildings, ground-floor light steel villas, factory warehouses, etc., which can meet the needs of self-built villas, new rural construction, old house renovation, scenic spot houses, tourism folk customs and other construction needs.
Economic performance: significant comprehensive benefits
Light steel structure has better comprehensive economic performance. Due to its light weight, the foundation cost can be relatively saved. The cross-section of the component is relatively small, which can increase the effective use of the building space. The steel structure is fast to construct and the construction period is short, which can reduce the pressure of loan interest on the owner and give full play to the use benefits of the building in advance.
Light steel structure technology has become a shining star in the field of modern architecture with its material characteristics, industrialization and environmental protection advantages, excellent seismic performance, wide range of applications and significant economic performance. Enterprises like Shijiazhuang Eiffel Steel Structure Co., Ltd. have made important contributions to the development and application of light steel structure technology with their professional technology and rich experience, and have also brought more possibilities and choices to the construction industry.
Light steel structure technology is reshaping the modern building pattern with its advantages of light weight, high strength, industrialization and high efficiency, and excellent seismic performance. From villas to factories, it not only shortens the construction period and reduces costs, but also can withstand a magnitude 9 earthquake, while reducing the amount of concrete by 7 times, making it an ideal choice for green buildings.
