Indeed, the better highrise buildings carry the universal traits of simplicity of thought and clarity of expression.It does not follow that there is no room for grand thoughts. Indeed, it is with such grand thoughts that the new family of highrise buildings has evolved. Perhaps more important, the new concepts of but a few years ago have bee monplace in today’ s technology.Omitting some concepts that are related strictly to the materials of construction, the most monly used structural systems used in highrise buildings can be categorized as follows:Momentresisting frames.Braced frames, including eccentrically braced frames.Shear walls, including steel plate shear walls.Tubeintube structures.Tubeintube structures.Coreinteractive structures.Cellular or bundledtube systems.Particularly with the recent trend toward more plex forms, but in response also to the need for increased stiffness to resist the forces from wind and earthquake, most highrise buildings have structural systems built up of binations of frames, braced bents, shear walls, and related systems. Further, for the taller buildings, the majorities are posed of interactive elements in threedimensional arrays.The method of bining these elements is the very essence of the design process for highrise buildings. These binations need evolve in response to environmental, functional, and cost considerations so as to provide efficient structures that provoke the architectural development to new heights. This is not to say that imaginative structural design can create great architecture. To the contrary, many examples of fine architecture have been created with only moderate support from the structural engineer, while only fine structure, not great architecture, can be developed without the genius and the leadership of a talented architect.
