Because there are only few experimental data available on the collapse test of shear wall, and most testing layouts were based on single-curvature bending test. In order to investigate the influential parameters of shear wall during collapse, 8 low-rise shear walls without openings were tested in this study, along with the varied parameters of the axial load and the horizontal shear reinforcement. Tests were carried out using reversed cyclic testing with a double-curvature bending layout. In addition to experimental study, available experimental results, relevant to shear wall, were collected. By using the ASCE/SE1 41-17 specification (ASCE 2017) and the proposed method by Tsao (2018), this study proposed a method to predict the displacement of the shear wall at collapse point. The proposed model could reasonably reflect the influence of either single or double-curvature bending effect on the collapse displacement of shear wall. Moreover, it comprehensively takes into the account of the acting axial load, the amount of vertical primary steel bars and the amount of horizontal steel bars, to make a reasonable prediction on the collapse displacement of shear wall.
