The Type of Steel Building Structures



The type of steel building structures includes the portal rigid steel frame, frame structure, truss structure, and grid structure. The advantages and disadvantages of different structural systems vary, and the forms of stress are also different.Get more news about steel structure building,you can vist our website!

Portal frame structure has simple force, clear force transmission path, and fast construction speed. It is widely used in industrial and civil buildings such as industrial, commercial, cultural, and entertainment public facilities.
Steel Building Frame Structures are flexible and can form a larger space. It is widely used in the multi-story, high-rise, and super high-rise buildings, commercial office buildings, conference centers, and other buildings.
The advantage of Steel Truss Structure is that small cross-section rods can be used to form larger cross-section components, which are often used in industrial and civil buildings such as roofs, bridges, TV towers, mast towers, marine oil production platforms, tower corridors, etc., with large spans or heights In the building.
The Steel Grid Structure is a high-order statically indeterminate space structure composed of many rods according to certain rules. The space is small in force, light in weight, rigid, and has good seismic resistance. It can be used as a gymnasium, exhibition hall, rain Roofs of buildings such as canopies, and hangars.
1. Portal Frame Steel Building Structures
The portal steel frame comprises a hot-rolled or welded section steel, cold-formed C/Z steel, and steel pipe as the main force-bearing components and adopts a light roof and wall structure. The Portal frame is the most common form of the light steel structure.

The rigid portal frame is a structure in which beams and columns are rigidly connected. It has the characteristics of simple structure, lightweight, reasonable stress, simple construction. Therefore, it is widely used in industrial, commercial, agricultural, and Institutional Buildings.
2. Steel Building Frame Structures
The steel frame structure is composed of steel beams and columns that can withstand vertical and horizontal loads. Columns, beams, bracing, and other members are rigidly or hingedly connected to form a flexible layout and create a larger space. It is widely used in a multi-story, high-rise, and super high-rise buildings, commercial office buildings, conference centers, and other buildings.
3. Steel Truss Structure
The steel truss structure is made up of several rods hinged at both ends of each rod. It can be divided into plane truss and space truss. According to the parts section, it can be divided into tube truss and angle steel truss. The truss is generally composed of the upper chord, lower chord, vertical rod, diagonal web, and inter-truss support. The amount of steel used in trusses is less than that of solid web beams, the structural weight is lighter, and the rigidity is greater.

The advantage of the steel truss is that it is used to form more significant members with smaller cross-sections. It is often used in roofs, bridges, TV towers, mast towers, marine oil platforms, and tower corridors of industrial and civil buildings.
4. Steel Grid Structure
The grid structure comprises many rods according to a specific rule, with small space stress, lightweight, high rigidity, and excellent seismic resistance. It is used as a gymnasium, exhibition hall, aircraft hangar.Steel structure workshops are divided into light steel workshops and heavy steel workshops. The workshop’s structural system is mainly composed of steel columns, wind columns, parapet columns, roof steel beams, crane beams, inter-column bracing, horizontal roof bracing, wall girt, roof purlins, tie bar, and other components. The primary structure is the portal steel frame, which can be single-span, multi-span, or multi-story, with an economic span of about 24-30m.
