| description | This study aims to determine the opportunities presented by diagrid and hexagrid systems in engineering and architecture and their relative strengths and weaknesses. In this study, three building models with 36 floors and 144 m high steel construction were designed using optimal angles identified through a literature review on diagrid and hexagrid systems. The diagonal angle of the designed model with diagrid system is 69° and the diagrid module includes three floors. The second model, the small modulus hexagrid model, has a diagonal angle of 41° and the hexagonal module includes three floors. The third model is the large modulus hexagrid model. This model is designed with a 60° diagonal angle and its modules contain six floors. It is assumed that the models are at earthquake ground motion level-1 according to Turkish Building Earthquake Code-2018 and the local soil class. For system behavior and comparison, the same live loads were applied to all building models, ETABS V.18 software was used for modeling and analyzing structural elements. Earthquake loads acting on the models as lateral forces are entered as equivalent earthquake load in ETABSV.18 software. Additionally, the models were compared with each other in terms of the amount of steel used, constructability, daylight benefiting capacities. It is considered that the study, which has evaluations in terms of the criteria that architecture and engineering ethics attach importance to, will make an important contribution to the literature. Consequently, it was understood that the model with the diagrid system was on more reliable side in dynamic analysis, and the model with the other two hexagrid systems was also reliable. However, in terms of the amount of steel used and daylight performance, especially it has been seen that the model with the large modullus hexagrid system is more advantageous. |
