The purpose of this thesis is to create basic design guidance for tall buildings and their aerodynamic modifications as a resource for architects, engineers, developers, and students. It aims to make a contribution to and strengthen particularly the architect̕s understanding of tall building design, that requires a high level of interdisciplinary approach, by providing a broad overview of the أtall buildingؤ with its general concepts; to demonstrate the importance of human element as a critical component in the design of tall building by clarifying the wind forces and resulting movements which cause discomfort to building occupants and create serious serviceability issues; and to show the significance of aerodynamic modifications as an effective design approach in terms of mitigating wind excitation. In order to achieve these purposes, firstly, a comprehensive literature survey, which includes the definition, emergence and historical background, basic planning and design parameters, and lateral load considerations of tall buildings is presented. Following a structural classification of the tall buildings, wind excitation, its negative effects on occupant comfort and serviceabilty issues, and the methods to control wind excitation are studied. Finally, the significance of aerodynamic modifications against wind excitation, which include modifications of building̕s cross-sectional shape and its corner geometry, sculptured building tops, horizontal and vertical openings through-building, are presented from the scholarship on this topic.

A study on main architectural and structural design considerations of contemporary supertall buildings Ilgin, Huseyin Emre; Ay, Bekir Özer; Günel, Mehmet Halis (Informa UK Limited, 2020-04-22) The design of supertall buildings (300m+) involves many professionals from several disciplines. The need for coordination among numerous experts, increases complexity of the entire process, which is typically conducted under the leadership of the architect, or sometimes the contractor. Consequently, the architects designing supertall buildings must be aware of architectural and structural design considerations and their interrelations. In this paper, the main architectural design considerations and structur...
Analysis of the limits of representation of architectural photographic images in periodicals Bakht, Nazlı; Güzer, Celal Abdi; Department of Architecture (2007) This study aims to analyze the limits of representation of architectural photographic images in periodicals within architectural media that shape today’s architectural production. This aim is accomplished in three sections; “examining the power of image in architecture”; “examining architectural media” and “examining the periodicals’ attitudes towards using architectural photography”. A case study is done to uncover the relationship between the photograph and the medium that it takes place on and determine ...
Understanding façade between design and manufacturing : a case study on high-rise office buildings in İstanbul Şener, Duygu; Güzer, Celal Abdi; Department of Architecture (2006) The thesis aims to examine how the formation of façades, that is, the interface with a dual response both to interior functioning and exterior urban fabric, is separated from the totality of architectural design by new technological developments and design intentions. This aim is accomplished in three sections, respectively: “analysis of the façade, the properties and formation process in time”; “examining the façade formation of the high-rise office buildings in Levent-Maslak area in respect to the analysi...
Exploring the potential of mat-building for the creation of universally designed environments Eren, Yasemin; Aközer, Emel; Department of Architecture (2004) The goal of this study is to reread the strategies of formal organization in architecture, which are called أmat-buildingؤ and أmat-urbanismؤ, exploring their potential to contribute to the creation of universally designed built environments in the 21st century. The idea of mat-building was first delineated by Alison Smithson in 1974, in her article أHow to Recognize and Read Mat-Building,ؤ by means of its traditional and modern examples. The concept of universal design was first used in 1970̕s and reinterp...
The dialogue of type and model in architecture Tunçbaş, Adil; Cengizkan, Ali; Department of Architecture (2006) The idea of type has always been a crucial factor in the field of architecture. Not only it works as a dominator in the design process of architecture but also it supplies the certain ways through which architecture communicates with the observer. In order to understand the interaction between architecture and the observer the idea of type appears as a critical point. This study will be an attempt to understand the dialogue of type and model in architecture. Throughout the research Anthony Vidler’s article ...
