One of the primary goals in tall building design is the optimum design
of service core where the vertical transportation, building services,
HVAC elements etc. are situated. Particularly for supertall (+300)
office buildings, a significant portion of the core space is occupied by
elevators when compared to the rest of the service core elements.
Actually, with the utilization of recently developed elevator
technologies, it is possible to decrease the elevator footprint area and
thereby to decrease the service core area. Nevertheless, the core of a
tall building usually is also a part of the lateral load resisting
system, namely as a structural core. This study aims to investigate the
effects of service core reduction which is a consequence of the elevator
footprint decrease on interior and exterior tall building structures.
Generic computer models of outriggered frame and framed-tube buildings
with 300m height (75 story) are produced. Then, the service core area of
both buildings is decreased considering the effects of recent advances
in elevator technology. First, the strength and the stiffness
constraints as well as serviceability of primary and reduced core
buildings are evaluated in terms of code-based design loads for each
outriggered frame and framed-tube structural systems. Then, primary and
reduced core buildings of outriggered frame and framed-tube structural
systems are compared in terms of the change in top drift to building
height ratio, the increase in leasable area and to access to natural
light.
