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