With the development of construction, the quantity of long-span buildings are more and more. And the structure of construction is improved according to the requirement of realizing the functions. The steel structure not only is satisfy to many requirements of long-span structure, but also have many other advantages, such as light structure, low cost, short terms, beautiful to look at and so on, so it will be widely used. As the representative architectures of steel construction, gyms, terminals and large factory buildings became the hot spot in the domain of Architecture, which depend on the novel appearance and the advanced technological program. Following I will state some advantages of steel buildings, let's go ahead.
1.Light weight, high strength, good resistance of earthquake
Generally, steel structure is lighter 30% than traditional reinforced concrete structure, and the strength is even better, too. Especially steels have the characteristics of toughness and plasticity, which could increase the earthquake resistance of steel structure construction.
2.Flexible space arrangement, short period of construction
It's flexible for separating the inside space of steel structure buildings, so the appearance of construction can be completely magnified. Especially in the area of long-span construction, steel structure can satisfy many requirements. That's why steel structure building can be widely used in many places, for example, airplane maintenance hangar, large industrial factory. And steel structure construction adopts the characteristics of assembling type, so it also have the advantages of quickly install and short period of construction.
3.Environmental friendly, sustainable development
Compared with traditional construction site, steel structure constructions have many merits, such as low noise, little dust, resource utilization pattern is simple, construction site is greener and so on. So far, the components of steel structure are produced in factory, then install on site. This process can effectively reduce pollution and construction waste. Besides, it's convenient to disassemble the steel structure buildings, which can increase the recycling ability.
