From the light, fast, good, save four aspects of the advantages of steel structure

From the development of recent years, the steel structure of China's buildings has gradually replaced the traditional brick-concrete structure, and there are many advantages in practical use. Earthquake resistance, wind resistance, durability, thermal insulation, sound insulation, health, suitability, speed, environmental protection, energy saving, which is consistent with the concept of promoting green buildings and assembled buildings in the country.

The steel structure has light weight and high strength

Compared with concrete and wood, the proportion of gravity density and strength is small, so in the similar building structure form, the steel structure has a large weight, a small section of the component, can withstand a larger load, can span a larger span, and is easy to transport and install.

1, so light

The steel structure raw material has good performance and high reliability. The steel is uniform, isotropic, large elastic coefficient, good plasticity and toughness, and is an ideal elastoplastic body. Therefore, the steel structure will not be suddenly damaged by accidental overload or partial overload, and can adapt to vibration load.

The steel structure has good seismic performance. Steel has high tensile and compressive strength, good plasticity and toughness. This uniform steel material allows the design to adapt well to the actual force. Energy consumption of connection structure, skin effect of envelope material, use of energy consumption components, etc. The structural system can prevent strong earthquake and play excellent performance. Therefore, the steel structure in the past earthquakes at home and abroad is a structure with little damage, and is recognized as suitable for seismic fortification areas, especially strong earthquake areas.

2, steel structure province, light

Simply from the current price of materials, the cost of steel structure is higher than that of concrete structure, but the steel structure is 50% faster than the concrete structure, so you can save a lot of time and cost, the total weight of the house is also more than 50% lighter than the concrete structure, so the basic treatment and transportation costs will decrease. Residential construction is a systematic project, including design, manufacturing, transportation, installation, maintenance, management and other aspects, so the overall steel structure is more "province".

Steel structure steel has the characteristics of recycling, and compared with other building materials commonly used at present, it is conducive to energy saving, energy saving, water saving and water saving. Of course, there are also defects in the steel structure, such as the problem of reduced fire resistance and corrosion resistance, but through the structural fire resistance design and correct fire prevention measures and anti-corrosion treatment, you can fully meet the requirements of use. In addition, with the use of new refractory steel and weathering steel, these shortcomings are gradually diminishing. In addition, the problem of low temperature brittleness of steel structures can be prevented by accurate design.

In recent years, China's construction industry has been a major user of energy, materials, water and other resources, promoting the development and popularization of steel structure is fully in line with the state vigorously advocate the establishment of a conservation-oriented society program, but also in line with the current state's sustainable development requirements for the construction industry.
