In recent years, steel structure has been increasingly used in the construction field, and its many advantages have made it the first choice for many construction projects, injecting new vitality into the sustainable development of the construction industry.
In terms of seismic performance, steel structure shows excellent advantages. The strength of steel is much higher than that of concrete, and its density is only about 3.2 times that of concrete. It weighs less at the same scale, and the use of steel in high-rise buildings, for example, can reduce the weight of the structure by about one-third. In the event of an earthquake, steel structure can absorb and consume seismic energy through its good ductility and elastic-plastic deformation, with strong resistance to strong earthquakes, greatly improving the safety of the building.
Wind resistance is also a highlight of steel structure. Section steel structure building light weight, high strength, good overall rigidity, deformation ability, building weight is only one-fifth of the brick structure, can resist 70 metres per second hurricane, effective protection of life and property safety.
Steel structure also has excellent durability. The light steel structure is composed of cold-formed thin-walled steel components, and the steel skeleton is made of super anti-corrosive high-strength cold-rolled galvanised sheet, which can avoid the impact of rust and corrosion of the steel sheet during construction and use, and increase the service life of light steel components, and the service life of most of the structures can be up to 100 years.
The steel structure also excels in terms of thermal and acoustic insulation and other comforts. The thermal insulation materials such as polyurethane insulation board used in its external wall have good thermal insulation effect, which can effectively avoid the phenomenon of “cold bridge” in the wall, and the thermal resistance value of pu polyurethane insulation board about 35mm thick can be equivalent to that of a 1-metre-thick brick wall. At the same time, most of the windows installed in the light steel system adopt insulating glass, and the sound insulation effect can be up to more than 40 decibels, and the sound insulation effect of the wall composed of light steel keel and thermal insulation material can be up to 60 decibels.
From the perspective of environmental protection and sustainable development, the materials and construction of steel structure houses are more environmentally friendly. From the perspectives of environmental protection and sustainable development, the materials and construction of steel structure houses are more environmentally friendly.
In addition, steel structure building is highly flexible and customisable in design and construction. It can be customised according to different needs to achieve a variety of unique architectural designs that can easily meet complex spatial layouts and functional needs.
Steel structure also has obvious advantages in terms of construction speed. With its standardised production of components and convenient on-site installation, it can greatly shorten the construction cycle and improve engineering efficiency.
It can be said that steel structure is playing an increasingly important role in the construction field with its many advantages such as strong seismic resistance, good wind resistance, good durability, high comfort, environmental sustainability, flexible design and construction, and fast construction speed, etc., and has a broad prospect for future development.
