A parametric investigation was conducted to determine the significance of selected structural and ground motion parameters on dynamic inelastic response of coupled wall structures. Structural parameters include: fundamental period, wall strength, beam‐to‐wall stiffness and strength ratios, coupling arm, clear beam span, gravity loads, and structure mass. Ground motion parameters include: earthquake frequency characteristics, duration, and intensity. A computer program and a moment‐rotation hysteretic model, including the effects of axial force‐flexure interaction, was used to conduct nonlinear dynamic analyses. Significance of each parameter on maximum force and ductility response is shown. The most significant parameters are identified as design variables. Relationships between design variables and response quantities are established.
