coupled shear wall with two-side connection and self-centering is a dual System, Including shear wall with Coupling and Self centering Which are joined together by truss elements in the alignment of the floors. In this dual system, beams coupling and plates have the function of energy dissipation and the self-centering frame has the function of reversibility. In this study, we investigate numerical studies on seismic performance of coupled shear wall and self-centering Primary pre-tensioning force and without pre-tensioning force with post-yield hardness under 12, 16 and 20% slope in ABAQUS software discussed. Therefore, 9 samples of 6 story coupled shear wall and self-centering Primary pre-tensioning force and without pre-tensioning force are designed in way performance-based plastic design and these samples have been subjected to and analyzed with push-over, cyclic, and time history analyzes. The results show that the coupled shear wall with two-side connection and self-centering Primary pre-tensioning force state with 20% slope stiffness compared to post-yield hardness, less residual drift, less relative lateral displacement distribution, Self-centering Better, less energy dissipation. Also, the distribution of relative lateral displacement and residual drift in self-centering Primary pre-tensioning force samples is less than without pre-tensioning force And in performance-based plastic design on relative lateral displacement distribution and residual drift performance is the same as force based design method, also, The distribution of the relative lateral displacement of the stories and the residual drift are the same in the self-centering Primary pre-tensioning force and without pre-tensioning force.
