摘要：
The post-fire mechanical properties of a prefabricated composite slabs consisting of thin-walled steel members and lightweight aggregate concrete was experimentally studied, and the displacements of the composite floor specimens was discussed. The experimental results showed that the ultimate load of the composite slab specimens after fire with using the stud shearing connectors was greater than that with using the new type shear keys made with thin-walled steel plate. The global stiffness and 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.
