What are the characteristics of steel structures

1、 Characteristics of Steel Structures

1. The steel structure has a relatively light self weight

The reliability of steel structure work is relatively high

3. Steel has good resistance to vibration and impact

The industrialization level of steel structure manufacturing is relatively high

5 steel structures can be accurately and quickly assembled

6. Easy to make into a sealed structure

7. Steel structures are prone to corrosion

8. Poor fire resistance of steel structure

2、 The grades and properties of commonly used steel for steel structures

1 Carbon structural steel: Q195, Q215, Q235, etc

2 Low alloy high-strength structural steel

3 High quality carbon structural steel and alloy structural steel

4 Special purpose steel

3、 Principles for material selection of steel structures

The principle of material selection for steel structures is to ensure the bearing capacity of the load-bearing structure and prevent brittle failure 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.

The four types of steel materials proposed in the "Code for Design of Steel Structures" GB50017-2003 are "suitable" for use, and are the first choice when conditions permit. The use of other types is not prohibited, as long as the steel used meets the requirements of the code.
