Abstract: Based on the multi-spring model, numerical simulation calculations for RC columns under reversed loading were carried out. The applied analytical model was verified by comparing the numerical results with the test data. In allusion to the deficiency in test, the parameter study was performed including the axial load ratio, loading path, loading amplitude, loading cycle number as well as variable axial forces. It is shown that the ductility of the columns with a large axial load ratio is significantly reduced. The ductility of columns under rectangular and diamond loading paths decreases rapidly as the amplitude ratio between two loading directions decreases. Varying the amplitude increment and the loading cycle number has little effect on the figures of skeleton curves. It is also shown that RC columns subjected to variable axial force loading exhibit an asymmetric hysteretic behavior, while the energy dissipation and the ultimate displacement are in substantial agreement with the ones subjected to constant axial forces.
