In recent high-rise buildings, a coupled wall system is adopted to resist lateral loads caused by wind or seismic. But as height of building increases, the structural stiffness plays significant role and the provision of outrigger system is benefited to give adequate stiffness to the structure against such lateral forces. Diagrid is recently evolved structural system resisting lateral loads due to wind or earthquake. The perimeter diagrid system creates triangular modules which are mainly responsible for resisting gravity as well as lateral loads caused by wind or earthquake. Provision of diagrid in high-rise building increases building stiffness and often makes lighter than conventional high rise buildings. As compared to conventional structural system, diagrid structure saves approximately 15% structural steel. This study presents the comparative results of diagrid and outrigger structural system for high-rise building of height 108 m subjected to lateral wind load. The analysis includes different building models with shear wall system, diagrid system and outrigger system. By using Gust factor method as per IS: 875 (Part-3)-1987, the lateral wind load is calculated by considering dynamic ‘along wind’ response. Hence the aim of this study is to analyze and compare different models by varying the angle of inclination and changing the location of outrigger. Comparison of analysis results is made in terms of top storey displacement, axial forces, material consumption and time period.Results show that provision of optimum angle of inclination for diagonal members of diagrid structure can efficiently reduce the deflection and enhance the structural stiffness. Also the diagrid system is proven to be more economical compared to outrigger system.
