Connection method of steel structure

There are mainly the following connection methods for steel structures:

‌Welding: Welding is a common connection method, suitable for steel structures that need to withstand large loads or require permanent connection. Welded connection is a rigid connection, which can withstand bending moments and shear forces, and is suitable for various environmental conditions.

‌Bolt connection‌: The bolt connection tightly connects the two components together through bolts, which is suitable for occasions where frequent disassembly is required. Bolt connections are divided into ordinary bolts and high-strength bolts, the latter with higher load-bearing capacity and better shock resistance‌

‌Rivet Connection‌: Rivet Connection Use rivets to secure two components together, usually in structures that require shear and tension. The construction of rivet connections is simple, but not as firm as welding and bolt connections‌

‌Pros and disadvantages of different connection methods and application scenarios‌:

welding:

Advantages: High connection strength, suitable for various environmental conditions, fast construction speed.
‌Disadvantages‌: Welding operations are required on site, which may cause welding stress and deformation.
‌Application Scenario‌: Applicable to steel structures that need to withstand large loads or require permanent connection.

Bolt connection:

Advantages: Easy to construct, easy to disassemble and replace.
‌Disadvantages‌: High preloading force is required and may loosen under high stress conditions.
‌Application Scenario‌: Applicable to steel structures that require frequent disassembly or maintenance.

Rivet Connection:

Advantages: Simple construction and low cost.
‌Disadvantages‌: The connection strength is low and not suitable for high-stress structures.
‌Application Scenario‌: Suitable for lightweight structures and occasions where frequent disassembly is required.
