철골조 모듈러 유닛의 현장시공 보-보 결합 구조체의 3시간 내화성능에 관한 실험적 연구

초록

This study aims to assess the 3-hour fire resistance capabilities of a beam-to-beam combination structure, mirroring the on-site assemblyfeatures of the modular construction method. A specific detail for the 3-hour fire resistance of the beam-to-beam combination structure wasput forth, followed by a non-load heating test utilizing a horizontal heating furnace. In this proposed detail, fireproof gypsum boards coverthe beams of individual modular units, the linear joint between on-site installed beams is filled with fireproof insulation or ceramic wool, anda fireproof sealant is applied for non-flammability assurance. The results from two rounds of 3-hour fireproof tests demonstrated satisfactoryfireproof performance.
