EIHE STEEL STRUCTURE is a good choice for you to build new airport steel structures. These airports are mainly architectural structures with steel as the primary raw material. Steel structures represent the mainstream solutions and technologies for terminal building construction. It has prominent advantages such as better durability, rapid construction, ability to withstand natural disasters, and low investment cost. Whether it is a hangar, a control tower or a terminal building, steel structure is one of the building structures that cannot be ignored at present.
The components of airport steel structure buildings are light in weight and have small cross-sections, which can make the interior space of the building more transparent and open. Nowadays, people's demands for airports not only need to meet their practicality but also their aesthetic needs. The flexible design of steel structures can satisfy people's demands for architectural aesthetics. Steel structure airport buildings with modern aesthetics are not only economical and practical, but also will become landmark buildings of a city or a country. For instance, Beijing Daxing International Airport, Singapore Changi Airport, etc.
Grid structures are typically composed of steel structure members connected to the main frame nodes. They are evenly stressed and provide more force support for the main frame. The concourse section of Terminal 3 of Beijing Capital International Airport has extensively adopted grid structures, which, with their efficient industrial production and reliable mechanical properties, support the vast waiting space.
The reticulated shell structure can be regarded as a grid structure with a curved surface form, perfectly combining the spatial force-bearing efficiency of the grid structure and the morphological expressiveness of the shell. It can create various elegant curved shapes, such as vaults and domes. The central hall of the main terminal building of Istanbul Grand Airport (iGA) features a magnificent reticulated shell structure roof. Its undulating curves not only create a unique architectural aesthetic but also achieve an open column-free space inside.
The tubular truss structure mainly uses circular or rectangular tubes welded into a lattice truss with a triangular cross-section. This structure is highly efficient, economical in material usage, and presents a balance between output and beauty in appearance, giving a light and modern visual impression. Terminal 3 of Shenzhen Bao 'an International Airport is renowned for its huge "manta ray" -shaped tubular truss structure inside. These interwoven trusses not only ensure structural stability but also serve as the most distinctive visual symbol of the terminal building.
The tensioned string beam/cable-membrane structure forms an efficient hybrid structural system by introducing high-strength cables or membrane materials to apply prestress to rigid beams or structures. It can achieve a span that is hard for traditional structures to reach with extreme lightweighting, featuring an elegant shape and a strong sense of transparency. The end of the concourse and the canopies at each entrance of Beijing Daxing International Airport widely adopt the tensioned beam structure. Its features include less material usage and a large span, creating an open and dynamic posture that welcomes passengers.
The main frame of the steel structure airport is composed of steel columns and steel beams, which are made of low alloy high strength steel. This type of steel can bear greater loads. Besides steel beams and steel columns, the main structure also has roof purlins and wall purlins. The purlins are made of C-shaped steel or Z-shaped steel and are used to support the roof and walls. To achieve the effect of earthquake resistance and wind resistance, steel structure airports will also be designed with a support system. The support system refers to connecting a single member between the steel beam and the steel frame to reinforce the stability of the steel frame. The enclosure system includes metal panels, skylights and glass curtain walls, etc. These materials are usually glass and aluminum alloy. It can not only increase the amount of natural light for buildings but also enhance their aesthetic appeal. In addition, to ensure the safety of the main structure of the airport, the components of the main structure will be pre-sprayed with fireproof and anti-corrosion coatings in the factory, which can increase the fire resistance limit of the steel structure to 3 hours.
Column-free open space: Steel structures, with their high strength, can achieve super-large spans of over 100 meters or even 200 meters. This means that in the core areas of the terminal building such as the check-in hall, waiting area and baggage claim area, the presence of columns can be completely avoided.
Airport operators can freely arrange check-in islands, retail stores, rest areas and other functional units without structural restrictions, and it will be extremely simple to adjust the layout when needed in the future.
All the steel components are completed in the factory through precise blanking, cutting, welding, drilling, sandblasting for rust removal and spraying.
The strength of steel is much higher than that of concrete, and it can withstand huge loads, including the self-weight of the structure, wind load, snow load, and equipment load.
At the end of a building's lifespan, steel can be nearly 100% recycled and transformed into new steel resources, significantly reducing construction waste and aligning with the concept of a circular economy. It has reduced the water consumption and wet operation pollution caused by concrete pouring.
High-quality anti-corrosion and fireproof treatment makes the later maintenance of steel structures very simple, mainly involving regular inspections. The maintenance cycle is long and the cost is low.
