Research on the Scale Fire Test and Fire Resistance of the One-Way Slab of a Metro

Buildings
To address the difficulty in conducting fire tests to verify the fire-resistance limit of large one-way slabs with heavy loads in a metro, a scale fire test method is proposed based on the bearing capacity calculation of the one-way slab under fire.
