摘要：The post-fire mechanical performance of a prefabricated composite slabs consisting of thin-walled steel beams with opening in web and lightweight aggregate concrete was experimentally studied, and the displacements of the composite floor specimens was discussed. The experimental results showed that the composite floors after fire had better plastic deformation capacity and greater residual bearing capacity. Type of the shearing keys, pull pieces between the precast concrete panels and the connection way of shearing keys to pull pieces had greater effect on the post-fire mechanical property of the composite slabs.
