Steel Structure Engineering

Understand the definition, types, characteristics, design and construction concepts of steel structures

1. What is a Steel structure（Steel Construction Engineering）?

Steel structure refers to a structural system that uses steel as the main material and assembles steel parts through welding, bolting or riveting processes according to certain design requirements and construction standards. Steel has the advantages of high strength, light weight and good durability, so steel structure is widely used in various fields such as construction, bridges, machinery, etc.

2.What are the types of steel structures?

Frame structure: Steel frame structure is a structural system composed of steel columns, steel beams and steel components, which is often used in multi-story or high-rise buildings. It forms a spatial support frame through transverse and longitudinal steel beams and steel columns.

Grid structure: Grid is a three-dimensional grid structure formed by the intersection of several steel pipes or steel bars, which is often used in large venues, hangars and other buildings. Its advantages are large bearing capacity, large span, and beautiful structural form.

Steel truss structure: Steel truss structure is a triangular grid structure formed by several rods connected by nodes, which is often used in large bridges, roofs, etc. Truss structure has good stability and is suitable for long-span buildings.

Steel plate structure: composed of steel plates and steel beams, steel plate structure is often used in some special building forms, such as underground structures and some buildings with special fire resistance requirements.

Reinforced concrete structure: Although this structure is formed by the joint action of steel bars and concrete, the steel bars bear the main force in it. This type of structure is usually widely used in steel structure buildings.

Composite structure: A structure that combines steel structure with other building materials (such as concrete). It usually uses steel structure as a frame and concrete as a filler. It is suitable for buildings that require large bearing capacity and strong stability.

High strength and light weight

Steel has high strength and is lighter than concrete structures.

Good seismic performance

Steel structures have excellent toughness and are earthquake-resistant in earthquakes.

Design flexibility

Steel structures have greater plasticity and adaptability, flexible shape, and are suitable for buildings that require special designs.

Fast construction speed

On-site construction only requires assembly, which greatly improves construction efficiency.

Durability and corrosion resistance

 Steel structures can resist wind, rain, corrosion and atmospheric pollution, and extend their service life.

Recyclability

Highly recyclable. When the building is demolished, the steel can be recycled again. management ...
