Type of Steel Structures

Type of Steel Structures:
The type of steel construction structures include a solid portal steel frame, frame structure, truss frame, and grid structure. The advantages and disadvantages of different structural systems vary, and the types of stress are also different.

Features and use of common types of steel structures:
The structure of the portal framework has a simple power, a clear power transmission system, and a fast construction speed. It is widely used in industrial and social structures such as industrial, commercial, cultural, and public recreation.
Metal Frame Buildings are flexible and can create a large space. It is widely used in high-rise, high-rise, high-rise buildings, commercial office buildings, conference centers, and other buildings.
The advantage of the Steel Truss Structure is that small cross-sections can be used to make large cross-section sections, which are commonly used in industrial and public buildings such as roofs, bridges, TV towers, mast towers, marine production platforms, tower corridors, etc. , with large spans or height in the Building.
The Steel Grid Structure is a structure with a maximum number of fixed joints with multiple rods according to certain rules. The space is small in strength, light in weight, sturdy, and with good earthquake resistance. It can be used as a gym, showroom, rain roof for buildings such as canopies, and hangars.
1. Portal Frame Metal Buildings
The metal frame of the portal consists of a section of hot-rolled or hot-rolled steel, a cold-built C / Z steel, and a steel pipe as components that carry energy and accommodate a lightweight roof and wall structure. Portal frame is the most common form of light metal structure.

A strong portal frame is a structure in which the beams and columns are firmly connected. It has features of simple structure, simple, reasonable stress, easy construction. Therefore, it is widely used in industrial, commercial, agricultural, and institutional buildings.
2. Steel Building Frame Structures
The structure of the steel frame is made up of steel beams and columns that can withstand direct and horizontal loads. Columns, beams, bracing, and other members are firmly attached or intertwined to form a flexible structure and create a large space. It is widely used in high-rise, high-rise, high-rise buildings, commercial office buildings, conference centers, and other buildings.
3. Steel Truss Structure
The steel truss structure is made up of several sticks that hang from both ends of each rod. It can be divided into flight truss and space truss. In part, it can be divided into tube truss and angle steel truss. The truss is usually composed of upper chord, lower chord, straight rod, diagonal web, and inter-truss support. The amount of metal used on trusses is smaller than that of solid web lines, the weight of the structure is light, and the durability is great.

The advantage of a metal truss is that it is used to build key members with small cross sections. It is commonly used on roofs, bridges, TV towers, mast towers, marine oil platforms, and tower corridors for industrial and public buildings.
4. Steel Grid Structure
The structure of the grid includes many rods according to a specific rule, with low pressure, light weight, high durability, and excellent earthquake resistance. Used as a gymnasium, exhibition hall, aircraft hangar.
