Tall building developments have been rapidly increasing worldwide. This paper reviews the evolution of tall building's structural systems and the technological driving force behind tall building developments. For the primary structural systems, a new classification interior structures and exterior structures - is presented. While most representative structural systems for tall buildings are discussed, the emphasis in this review paper is on current trends such as modeling and analysis. Consideration of site specific lateral loading due to wind or earthquake loads along with vertical gravity loads is important for finding the behavior of the tall buildings. The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. Analysis and design of buildings for static and dynamic forces is a routine affair these days because of availability of affordable computers and specialized programs which can be used for the analysis. Finally, the future of structural developments in tall buildings is envisioned briefly.
