- Characteristics of steel structure
1Steel structure has light weight
2 Steel structure work has high reliability
3. Steel has good vibration (shock) resistance and impact resistance.
4 Steel structure manufacturing has a high degree of industrialization
5 Steel structures can be assembled accurately and quickly
6Easily made into a sealed structure
7 Steel structures are prone to corrosion
8 Steel structure has poor fire resistance
- Grades and properties of commonly used steel structures
1. Carbon structural steel: Q235B, Q345B, Q355B, etc.
2. Low alloy high strength structural steel
3. Carbon structural steel and alloy structural steel
4.Special purpose steel
- Principles of material selection for steel structure
The principle of material selection for steel structure is to ensure the load-bearing capacity of the load-bearing structure and prevent brittleness under certain conditions. It is comprehensively considered based on factors such as the importance of the structure, load characteristics, structural form, stress state, connection method, steel thickness, and working environment. .
