During their service life, high-rise buildings and the associated nonstructural components endure various movements and deformations. Although the deformations and movements are not life threatening, inappropriate design of buildings and associated nonstructural components could induce expensive economic consequences in the long-run and, in order to ensure proper building behavior of the superstructures and the attached nonstructural elements, should not be ignored. In this article the possible deformations and movements of reinforced concrete high-rise buildings and the accommodation of the affected components are discussed. …
