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.

The impact of service core reduction in supertall buildings: a study on structural design, embodied carbon, and leasable floor area Fakıoğlu, Beste; Ay, Bekir Özer (2023-01-01) Optimizing the building core is a fundamental goal in tall building design The area dedicated to elevators, which are among the most area-consuming elements in the core, might be considerably reduced with recent technological advancements. This study investigates the trade-offs of core reduction resulting from the elevator footprint decrease in supertall buildings since the core usually serves as a significant member of the structural system. An analytical model with an outriggered frame system representati...
Evaluation of the effects of service core reduction on tall building structures Fakıoğlu, Beste; Ay, Bekir Özer; Department of Building Science in Architecture (2019) Optimum design of the service core where the vertical circulation systems, building services, HVAC elements etc. located, is one of the major tasks in tall building design process as it directly effects the net leasable area. Among others, the elevators are one of the most area consuming elements of service core, especially valid for supertall (+300m) office buildings. By making use of developing elevator technologies, decreasing the elevator footprint area and thereby decreasing the service core area is po...
The building performance of the metro station buildings' entrances Aksoy, Gökhan; Erman, Ercüment; Department of Architecture (2003) Station buildings are the most significant components of metro systems that combine underground facilities to the outer world, and include public life in itself. Thus, it is the main objective of that research, to put forward an acknowledgement documentation, which identifies the main design and construction problems of existing and under construction metro station buildings9 entrances, and which comes up with solutions to these problems. In the scope of thesis, foremost, basic terminology about station bui...
The Role of Aerodynamic Modifications in the Form of Tall Buildings Against Wind Excitation Ilgın, H. Emre ; Günel, Mehmet Halis (Middle East Technical University, Faculty of Architecture, 2007-6-01) Modern tall buildings go higher and higher with the advances in structural design and high strength materials. However, every advance in height comes with a new difficulty. Efficient structural systems, high strength materials, and increased height, result with decrease in building weight and damping, and increase in slenderness. On the other hand, as the height and slenderness increase, buildings suffer from increased flexibility, which has negative effects in wind loading. Flexible structures are affected...
