| Title | A Study on the Benefit Evaluation of Fire Protection methods for Steel Structures | ||
| Keyword | |||
| Abstract | Steel structures have been widely used in modern construction projects due to their high strength and construction efficiency. However, steel materials rapidly lose strength under high-temperature fire conditions, potentially leading to structural collapse. Therefore, selecting effective fireproofing methods to ensure fire resistance has become a critical issue in architectural design and engineering construction. This study conducts an in-depth investigation and analysis of three common fireproofing methods for steel structures: spray-applied fireproofing, intumescent fireproof paint, and concrete encasement, evaluating their construction processes, economic efficiency, and structural performance. The results indicate that spray-applied fireproofing offers rapid construction and cost-effectiveness but is susceptible to environmental conditions, resulting in relatively rough surface finishes. Intumescent fireproof paint provides excellent aesthetic quality and flexible application, yet it involves higher costs and requires strict control of construction conditions. Concrete encasement, although having higher initial costs and more complicated construction processes, demonstrates superior fire resistance and lower long-term maintenance costs, making it particularly suitable for high-rise buildings and essential public facilities. in addition, through case studies and expert interviews, the research finds that concrete fireproofing layers significantly improve the structural sectionˇ¦s moment of inertia, thereby enhancing the deformation resistance and overall stability of the structure. In summary, the research recommends selecting appropriate fireproofing methods based on building usage, budget constraints, and construction requirements to achieve an optimal balance among structural safety, construction quality, and cost control. These findings provide valuable references for future fireproof construction planning of steel structures. |
