A problem of earthquake-response drift constrained design of a coaxially coeccentric shear building with a basement of specified high stiffness is an inverse-primary mixed problem. No such successive improvement procedure as developed for a shear building without a basement can be applied to the problem here since not only the story stiffnesses but also first floor displacement relative to the ground are the unknowns. An efficient method is developed for the inverse-primary problem in the form of Taylor series representation of their earthquake-response drift constrained designs in terms of a flexibility parameter of the basement stiffness about the known earthquake-response drift constrained design of a shear building without basement. Such a Taylor series representation is not only useful as a solution procedure but also significant as a formula representing the effect of the basement on the upper story stiffnesses.
