Marc. The rationality and reliability of the FE model was verified through the comparison between the FE analysis results and the experimental results of the five SRC shear wall specimens. Based on the proposed FE model, parametric analysis was carried out to study the effect of the axial compression ratio and steel ratio on seismic behavior of SRC shear walls. The analysis results showed that the bearing capability of the SRC shear walls improve with the increase of the axial compression ratio. The deformation capability of the SRC shear walls decreases rapidly with the increase of the axial compression ratio. The bearing capability and deformation capability of the SRC shear walls irrprove with the increase of the steel ratio. However, the deformation capability of the SRC shear walls impmve not so significant under high axial compression ratio.
