“…Due to the ongoing urbanization and technological developments, the number of tall and supertall buildings (≥300m high) in the world is increasing exponentially (Karjalainen et al, 2021;Tulonen et al, 2021;Ilgın, 2022;Ilgın et al, 2022a;Ilgın and Karjalainen, 2022). In the initial phase of tall building construction, building designs were simple and most of the tall buildings had regular traditional configurations e.g., square, and rectangular prisms (Ilgın and Günel, 2007).…”

Today, supertall buildings can be constructed in unusual forms as a pragmatic reflection of advances in construction techniques and engineering technologies, together with advanced computational design tools for architectural design. As with many other buildings, architectural and practical principles play a crucial role in the form of a supertall building, where aerodynamic behavior shaped by wind-induced excitations also becomes a critical design input. Various methods are used to meet the functional needs of these towers and reduce excitations, including aerodynamic modification methods directly related to the building form. Tapered forms are one of the most frequently used and most effective methods in today's skyscrapers, which significantly affect architectural design. To date, no study has been conducted in the literature that provides an understanding of the interrelationships between tapered building forms and main planning criteria, considering the aerodynamic design concerns of the tapering effect in supertall buildings (≥300 m). This important issue is explored in this article with data gathered from 41 supertall case studies, considering location, function, structural system, and structural material as well as the aerodynamic taper effect. The main findings of the study highlighted the following: (1) Asia was where tapered towers were most favored, with a wider margin in all regions; (2) mixed-use was the most preferred function in selected supertall buildings with tapered form; (3) outriggered frame systems were mainly used; (4) tapered supertall cases were mostly built in composite; (5) the sample group included 17 cases that used the tapering effect with aerodynamic design concerns, some of which were accompanied by corner modifications. It is believed that this study will be a basic guide for design and construction professionals including architectural and structural designers, and contractors.

“…One of the important ways to cope with the dramatically growing human population with a population increase of 2.5 billion by 2050 is the skyscraper, that is, the vertical city paradigm [1]. Politicians, planners, and architects began to pay more and more attention to this paradigm [2]. Also, many cities around the world adopt tall buildings as their main building typology in the 21 st century [3].…”

To date, no research has been carried out in the literature that gives insight into the relationships between freeform and key design parameters in supertall towers (≥ 300 meters). This critical subject is investigated in this paper with data collected from 39 building cases, taking into account building function, load-bearing system, and structural material as design parameters. The key findings of the paper highlighted the following: (1) the only core typology was central core type; (2) mixed-use and office were the most favored functions; (3) the most favored system in freeform supertall tower projects was outriggered frame system; (4) composite construction was common among supertall towers and its closest follower was reinforced concrete; (5) building functions other than hotel exceeded 500 m in free form; (6) in the sample group, freeform buildings with outriggered frame and tubular systems exceeded half a kilometer as well; (7) both composite and reinforced concrete freeform towers pushed the limits of height considerably; and (8) as the number of some supertall tower buildings (such as hotel buildings) was not adequate, it did not seem possible to derive a scientific interrelation between the height of the building and the corresponding planning parameter. It is thought that revealing the current state of the free forms, which are among the most preferred skyscraper forms today, will shed light on the supertall building designs to be made in the future.

“…The utilization of timber in the construction sector has been revived since the mid-1990s [1,2], and particularly in the last 10 years [3,4], due to environmental concerns, urbanization challenges, and productivity in the construction industry [5][6][7]. Since the end of the twentieth century, the question of how to deal with the increasing scarcity of resources has been at the center and the need for renewable (building) materials has come to the fore, especially in the building construction industry [8].…”

Since the end of the twentieth century, the question of how to deal with the increasing scarcity of resources has been at the center and the need for renewable materials has come to the fore, especially in the construction sector. A possible solution to these environmental challenges is represented by the development of engineered timber products, which allowed the realization of tall timber structures. Their main drivers are decarbonization, forest management, and timber life cycle, urbanization, and densification, productivity in the construction industry, and the benefits of using timber indoors. In this context, this chapter will analyze data from the 10 tallest timber building cases to enhance the understanding of contemporary trends. Data are collected through literature surveys and case studies to analyze the main architectural and structural design concerns to contribute to the knowledge about the growing tall timber structures around the world. By revealing up-to-date features of the tallest timber towers, it is thought that this chapter will contribute to aiding and directing key construction professionals such as architects, structural engineers, and contractors, in the design and construction of future tall timber building developments.
