<input id="uauy4"></input> 1. The steel structure has a relatively light self weight
2. High reliability of steel structure work
3. The steel has good vibration (shock) resistance and impact resistance
4. The industrialization level of steel structure manufacturing is relatively high
5. Steel structure can be installed accurately and quickly. 6. It is easy to make a sealed structure
7. Steel structures are prone to corrosion
8. The principle for selecting materials for steel structures with poor fire resistance is to ensure the load-bearing capacity of the load-bearing structure and avoid brittle failure under certain conditions. Factors such as the importance of the structure, load characteristics, structural form, stress state, connection method, steel thickness, and working environment are summarized and considered.
The four types of steel proposed in the "Code for Design of Steel Structures" GB50017-2003 are "suitable" for use, and are the first choice when conditions permit. Other types of steel are not prohibited, as long as the steel used meets the requirements of the code.
