1. Steel structures have a relatively low self-weight.
2. Steel structures demonstrate high operational reliability.
3. Steel possesses excellent resistance to vibration and impact.
4. The manufacturing of steel structures is highly industrialized.
5. Steel structures can be assembled accurately and rapidly.
6. In certain large-scale public building projects-such as the roof steel structure for the swimming venue at the Jinan Yellow River Sports Center-steel structural systems are complex, individual components are massive in scale, and construction precision requirements are exceptionally high.
7. Steel structures allow for expansive interior spaces.
8. They can be easily constructed as sealed structures.
9. Steel structures are susceptible to corrosion.
10. Steel structures possess poor fire resistance.
