A wall panel zone is a region in which forces from connecting wall segments are resolved. Four different types of wall panel zones are described. Among these, the case of a wall panel located under an aligned stack of openings in a coupled wall is examined closely. Instances in which such panel zones failed during past earthquakes are presented. Laboratory tests and analytical studies are used to define wall panel zone force demands and capacities. It is shown that simple mechanics and existing design expressions can be used to design wall panel zones against shear failure.
