In this work, the parametric study is performed on the numerical models of one-storey and four-storey composite shear walls that are made in real dimensions. In this regard, the structural performance of double skin composite shear walls (DSCSW) and Reinforced DSCSW (RDSCSW) under monotonic/cyclic loading are examined and their behavior are compared with the innovative composite shear wall (ICSW). The FE models of small-scale laboratory specimens are also created in ABAQUS software. Hereof, there is a need to reinforce the two ends of the DSCSW walls with a boundary layer column and also to evaluate their resistance. For this purpose, the behavior and performance of the examined models (ICSW, DSCSW, and RDSCSW) with three ratios of H / L (in scales of 1:1, 2:1 and 3:1) are compared. According to the results, the shear strength, initial stiffness and energy dissipation capacity of RDSCSW models are higher (20%) than DSCSW models and also performance of the DSCSW models are better (8%) than ICSW models. Finally, RDSCSW is one of the new structural systems utilized to resist earthquakes and that has better a hysteretic behavior than the similar shear wall.
