This paper presents the results of an experimental study on the failure mechanism, strength, ductility and energy dissipation of reinforced concrete core walls subjected to different axial load and horizontal loading. Five core wall models were built and tested to failure under the combined action of constant axial load and reversed cyclic lateral loading. The objective of this test is to investigate the effect of parameter variation of axial load ratio and shear compression ratio on the behavior of reinforced concrete core walls. Finally, the axial load ratio is found to have an important effect on the seismic behavior of reinforced concrete core walls.
