     due to architectural limitations, in many cases the rc shear walls have to be extended in plan in different directions at one location making them a 3d configuration. modeling and analysis of such walls is very challenging and only a few studies are available on them. in this research a number of 3d shear walls are considered with different shapes and heights. they are modeled for nonlinear dynamic analysis in abaqus software using an exact moment-shear interaction model. a suit of appropriately selected and scaled ground motions are used for analysis. the envelope of the nonlinear force-displacement responses is used to develop a macro model of the same walls consisting of an elastic wall throughout in series with a nonlinear moment-rotation spring at the base in opensees. it is shown that the developed model can predict the maximum responses with a very good accuracy in a much less time.
