Portal steel frame is a very common and mature building structure. The construction of the portal steel frame originated in the mid-20th century in the United States. Compared to traditional structures, the portal frame has significant advantages. Therefore, it has quickly been promoted globally and has become the mainstream structure for factories, supermarkets, exhibition halls, warehouses, and other buildings.
The portal frame structure is a type of lightweight steel structure. It has many outstanding characteristics that make it a common structural design in the industrial sector.
Advantages of portal steel frame
- Simple structure with high space utilization.
The buildings of this structure mainly consist of columns and various beams. There are not too many columns inside the building, providing a large open and unobstructed space. This feature makes the portal frame the preferred choice for factories, warehouses, stadiums, and other buildings.
- Certain structural strength and low cost.
The most important structural feature of the portal frame is the rigid connection at the column and beam joints. This structure can effectively resist wind forces and those generated by cranes, maintaining structural stability. Additionally, during construction, many columns and beams are connected using variable cross-sections. This connection method fully utilizes the properties of each component, saving costs.
- High industrialization degree of components and short construction period.
Although there are size differences, the columns and beams of the portal frame structure are standard products available in factories. Such components allow for easy control of factory quality and supply cycles. At the same time, the construction of portal frame structures only requires bolt connections or welding, which is relatively simple. These characteristics greatly shorten the construction period of portal frame structures.
