Based on the plane section assumption and the characteristic of self compacting concrete (SCC) composite shear walls, the calculation method of yield displacement was established and tested by the experimental results of five SCC composite shear walls. Then, the interrelated relationships among the axial compression ratio, the strength of concrete, the reinforcement ratio of distributing bars, the reinforcement ratio of anchor bars and the yield displacement were obtained. The results show that choosing the reasonable reinforcement ratio of anchor bars, limiting the axial compression ratio and increasing the characteristic value of strength of concrete can improve the yield displacement of SCC composite shear walls. The reliability of the method is certified through the comparison of the analysis results and the experimental results.
