Effecting Factors of Skeleton Curve for High Strength Concrete Column Confined with High-strength Stirrup

Based on the experiment on high strength concrete column confined with high-strength stirrup, the influence of stirrup strength and stirrup spacing on skeleton curve of the ordinary strength and high-strength stirrup concrete components during the whole failure process of the components are studied. And the results show that it not only can provide the necessary theoretical basis for application of high-strength stirrup confined concrete, but can give good reference value to the seismic design of reinforced concrete structure.
