State-of-the-art Disaster Resistance Performance of Steel-Recycled Concrete Composite Columns

In this paper, the state-of-the-art bending performance, seismic performance, and fire resistance performance of steel-recycled concrete composite columns were discussed associated with its deficiencies, and the problems that need to be further studied were pointed out. It shows that the bending performance and seismic performance of composite columns with recycled concrete is slightly weaker than those with normal concrete, while their fire resistance shows a little stronger. The steel-recycled concrete composite column with reasonable design can be used for recycled concrete composite structures.
