Abstract

High-rise buildings are an increasingly common type of commercial and residential buildings because of their large capacity on small lands. These buildings appear with different architectural features with the development of new building materials and technologies. In this study, plan shapes and facade forms used in high-rise buildings are investigated considering the ten tallest buildings in the world. Architectural characteristics of the considered high-rise buildings are briefly summarized based on the results of detailed investigations. Structural systems of the buildings are analyzed, particularly in plan shapes. As a result, it has been observed that different plan shapes and facade forms are determined based on building-specific reasons. High-rise buildings are designed with different architectural plan forms in accordance with the functional requirements. These plan forms are also created with various common areas to strengthen the relations of building users with each other. On the other hand, the most important factor in the current design practice of these forms is the wind load and the forms are generally designed considering the results obtained from wind tunnel analysis. The use of rounded lines in plan and facade forms allows the wind load affecting the building to decrease and the user’s comfort to increase. Another important factor in the design is the creation of an aesthetic appearance on the exterior of the high-rise building. In particular, the facade forms of such buildings are designed in accordance with the design principles for increasing the aesthetic perception of the building, as well as the image of the city.
