Abstract
En 中文
Steel modular buildings are increasingly applied across various building types; however, effective fireproofing design remains a challenge, particularly for mid-rise structures. Conventional fire protection methods focus on individual structural members (e.g., columns, beams, and walls), leading to constructability limitations and material inefficiencies. Existing fire-resistance standards are not well-suited for modular systems. This study proposes a module-unit fireproofing method that eliminates the need for member-level treatment. Full-scale fire tests were conducted for 1-hour and 2-hour ratings. Results confirmed that steel frame temperatures remained below the average limit of 538 degrees C, and insulation criteria of 165 degrees C were satisfied. A 3D finite element thermal model was also developed and validated against test data. The model showed strong agreement with the experimental results, demonstrating its potential as a predictive tool for future modular fireproofing design.
