Performance Evaluation of Diagrid and Hybrid Diagrid Structural Systems for Tilted Tall Structures

In the present scenario, the viability of the diagrid structural system in tall structures is extensively investigated across the globe due to the rapid expansion of urban development. This study modifies the diagrid structural system by additional peripheral columns to enhance the performance of the complex or tilted diagrid structures, namely the hybrid diagrid system. The inclination angle was kept at 11.5 degrees to compare the performance of tilted diagrid and hybrid diagrid systems. The performance of 36-storey straight and tilted diagrid and hybrid diagrid systems were analyzed and compared for gravity and earthquake load for each structure. The Response spectrum analysis is used in this study. The displacement, time period, and story drift results were compared. The results show that the displacement, time period, and story drift of the hybrid diagrid structural system is less compared diagrid structural system in both straight and tilted conditions. It is concluded that the hybrid diagrid structural system has adequate functionality to achieve future vertical expansion of metropolitan cities.
