INVESTIGATION ON THE EFFECT OF DIAGRID STRUCTURAL SYSTEM ON DOUBLE SKIN FACADE FORMATION IN HIGH-RISE BUILDINGS

The development of industrialization and technology since the 20th century has led to an increase in the population and consequently energy requirements, the depletion of natural resources and many environmental problems. High-rise buildings cause serious energy consumption as a result of the high heat losses and gains due to the advanced technologies which is used in the construction and operation of the building and due to the high glass ratios. Aim: The aim of this study is to examine the effect of the diagrid system on the double skin facade formation in high-rise buildings through examples, and to provide guidance on the selection of the appropriate system for designers. Method: By using the qualitative research method, the characteristics of the sample tall buildings using the diagrid system and the double skin facade system were examined and a comparative analysis was made under certain headings. Results: In all of the buildings in the sample group, it is seen that the double skin facade system is configured in the corridor type. Considering the reasons leading to the corridor-type double skin facade formation of the examined structures, it is noteworthy that the diagrid structural system modules are emphasized on the exterior skin. In addition, the ring beam level plays a decisive role in the horizontal division of the double skin facade air space. Conclusion: In this context, it has been concluded that the diagrid system in the sample buildings forces the double skin facade system to a corridor type structure due to its tendency to emphasize the inclined columns on the exterior and its structural necessities.
