This study analyzed the stress–strain curve of stirrup restraint ferrous tailing concrete by test and theoretical analysis. Twenty short column in strength grade 5 are used in the test with WC30, WC35, WC40, WC45 and WC50. The stress–strain data is achieved after the axial compression behavior test. It is found from the stress–strain curve that the stress–strain relationship is similar with natural sand concrete. Moreover, the whole stress–strain curve equation of stirrup restraint ferrous tailing concrete is put forward. The calculation results show that the data calculating by the equation are in good agreement with the experimental data.
