No matter how complex the steel structure is, its composition principle is the same. It is composed of simple components connected together by bolts or welding to form a majestic overall building or structure.

Each basic component is made of section steel or steel plate. Let's take a look at what is the combined section of section steel and steel plate.
1.Channel steel
2.Angle steel
3.Square steel tube
4.I-beam
5.Round steel pipe
- Combined sections made of welded steel plates
1.A composite section made of three steel plates welded - H-beam steel column
2.Seven steel plates are welded to form a combined section-cross-shaped steel column
- There are three main ways to connect components: bolts, welding, and rivets
1.Bolt
Bolted connections for frame beams
Bolted connections for frame columns
Torsional shear high-strength friction bolts
Ball type anti-theft nut
2.Weld connection
3.Rivet connection
It is basically no longer used. Around 1900, it was widely used in high-rise steel structures in the United States, including the Eiffel Tower in France built in 1887.
