Steel Structure Building

1.the connection method of steel structure:

    welding connection or bolt connection

2.Steel structure design common norms are as follows:

• "Steel Design Code" (GB50017-2003)
• "Cold-formed steel structure technical specifications" (GB50018-2002)
• "Construction Quality Acceptance of Steel" (GB50205-2001)
• "Technical Specification for welded steel structure" (JGJ81-2002, J218-2002)
• "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)

3.The characteristics of steel

• Light weight steel structure
• Higher reliability of steel work
• Steel anti-vibration (earthquake), impact and good
• Steel structure for a higher degree of industrialization
• Steel can be assembled quickly and accurately
• Large steel interior space
• Likely to cause sealing structure
• Steel corrosive
• Poor fire-resistant steel
• Recyclable steel
• Steel shorter duration

4.Commonly used steel grades and performance of steel

• Carbon structural steel: Q195, Q215, Q235, Q255, Q275, Q345,etc.
• High-strength low-alloy structural steel
• Quality carbon structural steel and alloy structural steel
• Special purpose steel
