    Abstract

    Presented are the results of nonlinear pushover analyses of the hybrid coupled wall (HCW) prototypes designed and discussed in a companion paper. The objectives of the analyses are (1) to study the effect of the coupling ratio on system response; and (2) to evaluate existing design guidelines for HCWs. The discussion addresses target displacements, displacement profile, base shear, wall reactions, story drifts over the height, wall plastic rotations, shear distortions, coupling beam rotations, wall-beam connection response, crack patterns, concrete crushing at critical locations, and system overstrength. The suitability of HCWs for use in regions of high seismic risk is discussed.
