Abstract:
Due to the increasing number of people and activities in cities, while the amount of land used is limited, high-rise buildings are increasing rapidly around the world to meet the need for new living spaces and commercial areas. In recent years, thanks to the development of computational tools and technological solutions, the design of tall buildings has shown significant improvements. This has led to the construction of innovative structural systems, such as the diagrid load-bearing system, which enable high structural performances and remarkable architectural solutions. Research on the structural performance and environmental effects of the different geometric configuration of the diagrid carrier system in high-rise buildings is limited. The aim of the study is to determine the role of structural system design on the environmental effects of the structure by investigating the effects of module geometries of different angles and densities in the diagrid structural system in high rise buildings, on the reflection of internal structural stability and efficiency, on the amount of steel material and daylight illumination level, and therefore on the annual primary heating and cooling loads. A structure with a 42-storey steel diagrid carrier system is assumed in the Eskişehir Highway Region of Ankara. Alternative models were modeled and analyzed in the SAP2000 V20 program. Concrete performance evaluations of the carrier elements contributing to the formation of the form were made by making a comparative analysis of the three selected systems. Rhinoceros software ClimateStudio plugin was used for daylight analysis. How architectural design decisions and structural design requirements mutually affect the structural behavior, architectural design and indoor comfort in high-rise buildings is discussed with a holistic approach. According to the data obtained, a structural language has been tried to be developed that can be a guide in determining the facade geometry in the diagrid system high-rise design.
