Abstract: Construction of super tall buildings across the globe has become more and more challenging. In some cases, code prescribed high lateral load considerations for wind and seismic make it prohibitive to conceive tall buildings and in some other case empirical results of geotechnical conditions recommend foundation system that are un-constructible. This paper addresses the various aspects of Optimal Design that make super tall buildings, more viable around the globe. Of particular interest, the Performance Based Design (PBD) is discussed and examples projects are provided to illustrate the benefits of using PBD. These advantages include various perspectives of super tall building design and construction, including the wind, seismic, foundation, structural node, and constructability.
