Research on Axial Compression Performance of Steel & Steel Pipe Reinforced Concrete Columns

Abstract:

Through axial load bearing capacity test of eight steel & steel pipe reinforced concrete composite columns, the working mechanism, the ductility and the ultimate bearing capacity of the composite columns were studied, and the main factors affecting the performance of the composite columns are discussed, including concrete strength and the ferrule coefficient. The results show that the collaborative force of steel, steel pipe and concrete can effectively improve the bearing capacity of the columns, delay or inhibit the spread of oblique shear cracks in concrete and improve the ductility of the columns.
