Abstract—While the early design of tall buildings culminated
with the dominance of the International Style, today’s pluralism
in architectural design has produced tall buildings of many
different forms, including more complex forms, such as twisted,
tilted, tapered and free forms. This paper presents
performance-based structural system design options for
complex-shaped tall buildings. For each complex form category,
tall buildings are designed with various structural systems, such
as braced tube, diagrid and outrigger systems, and the
structural performance of each system, in conjunction with the
building forms and heights, is studied. Parametric structural
models are generated to investigate the impacts of varying
various important geometric configurations of complex-shaped
tall buildings, such as the rate of twist, angle of tilt, angle of
taper and degree of fluctuation of free form. The parametric
models are exported to structural engineering software for
analyses, design and comparative studies. While an emphasis is
placed on the structural performance of complex-shaped tall
buildings, architectural and construction issues are also
discussed holistically.
Index Terms—Twisted tall buildings, tilted tall buildings,
tapered tall buildings, freeform tall buildings, diagrids, braced
tubes, outrigger structures.
