In Hybrid-Wall-System (HWS) structures composed of coupled shear walls and steel perimeter frames, the vibration mode under earthquake is expected to be the first mode due to existence of the shear walls. Since the vibration mode does not change much with each other whether HWS structure is in elastic or inelastic ranges, the structural performance can be represented by the base-shear coefficient versus horizontal displacement relation of equivalent single-degree-of-freedom system. Using this feature, the capacity spectrum method is applied to estimate the earthquake response of HWS structures in this paper Also examined is a method of evaluating the damping property of HWS structures which is to be considered for a response spectrum referred to as the demand spectrum in this method. A 1/3-scaled 12-story, coupled shear wall tested by the authors is analyzed using this method.
