Abstract：Four shear walls with flanges of HRB600 grade rebars and one shear wall with flange of HRB400 grade rebars were designed and tested under reversed cyclic horizontal forces. The main aim is to study their performance differences and the influence of reinforcement ratio and axial compression ratio on seismic anti-shear performance. It is shown that the ultimate shear capacity of shear wall with HRB600 grade rebars is lower than that with HRB400 grade rebars. HRB600 grade rebars fail to yield when the ultimate shear capacity is reached. While the crack width of shear walls with HRB600 grade rebars is smaller and the deformation capacity is better than that with HRB400 grade rebars in later period. Moreover, the finite element analysis software VecTor2 is used to analyze the main factors which affect the shear capacity of low rise shear walls with high-strength rebars. In the end, the formula for design value of HRB600 grade rebars is obtained.
