摘要：The post-fire mechanical behaviours of the composite floors consisting of lightweight aggregate concrete and thin-walled steel members were experimentally studied, and the test result of the composite floor specimens was discussed. The experimental results showed that the residual load-bearing capacity of the composite slabs after suffering hydrocarbon fire can be effectively improved by increasing the wall thickness of transverse sub-members appropriately. The ultimate load of the composite slab specimens after fire with using the commonly used stud shearing connectors was larger than that with using the shear keys made with thin-walled steel plate.
