20, are analyzed nonlinearly under time histories. Stiffness and strength degradation, nonlinear behavior of reinforced concrete sections and their energy dissipation in cyclic loading are taken into account. This study tries to find stiffness ratios for frame in wall-frame structures which lead to
safe and best nonlinear performance at different level of hazard. Methods are proposed to define wall, frame and wall-frame stiffness in multistory structures. Based on result of this study the minimum frame strength equal to 25% of lateral forces is not accurate and it could be decreased safely, however the best performance would be possible with higher frame stiffness and strength ratios.
