Evaluation of fire-resistance performance for modular structures based on fireproof coating types

This paper conducted fire resistance experiments on components used in modular structures. The fire resistance tests were conducted on various fireproofing materials, including conventional fire-resistant gypsum boards, fireproof paint, and Fiber plast. A total of 8 test specimens were prepared, consisting of 4 beam components and 4 column components. For the beam components, a single material was used for fireproof coating, while for the column components, three were coated with a single material, and one utilized both gypsum board and Fiber plast simultaneously. The experimental results were evaluated against the specified fire resistance criteria for each test specimen. Additionally, finite element analysis was performed on the experimental results, particularly focusing on the newly introduced Fiber plast. The analysis aimed to interpret the variables related to finite element analysis and propose an optimal thickness based on the experimental findings.
