They offer excellent seismic performance, particularly in reducing inter-story drift and providing greater lateral stiffness. This study uses ETABS-2020 to analyze the structures under various loading conditions, including static earthquake forces, dynamic earthquake forces (per IS: 1893 – (part-1) 2016 guidelines), and wind dynamic forces (per IS-875 (part-3)-2015). The structures are designed based on IS: 800-2007, and parameters such as story displacement and story drift are observed. The study compares different types of lateral load resisting systems to determine the most effective and economical system for resisting lateral loads such as wind and seismic loads. The lateral load resisting systems under investigation include diagrid, belt truss systems for 20, 30, 40, and 50 story structures with plan dimensions of 50m X 50m. Additionally, the study analyzes various percentages of plan dimension in the diagrid structure.

India has experienced numerous natural disasters in the past, such as earthquakes and tsunamis, and some regions in the country are witnessing a rise in the frequency of earthquakes. While earthquakes cannot be predicted, their damages can be mitigated by incorporating various lateral load resisting systems in building designs. Buildings are subjected to two types of loads - vertical loads due to gravity and lateral loads due to earthquakes and wind. Lateral load resisting systems are incorporated to resist these forces. In multi-storey buildings, lateral loads are the governing factor in design. There are various lateral load resisting systems that can be used, such as shear walls, belt trusses, outriggers, belt truss + outrigger systems, diagrids, staggered trusses, tube-in-tube systems, and more. These systems are designed to increase the stiffness of the structure and absorb lateral forces generated during earthquakes and wind events. They provide additional strength and stability to the building, reducing the risk of structural damage and collapse. By incorporating these lateral load resisting systems, high-rise buildings in India and other earthquake-prone regions can enhance their seismic resilience and safeguard against potential disasters. With the increasing vertical development of buildings due to limited availability of land in recent years, high-rise structures are becoming slenderer. As the height of a building increases, lateral loads, including wind and seismic loads, become more dominant than gravity loads in governing the design. Therefore, it is crucial to incorporate effective and economical lateral load resisting systems in high-rise building designs to ensure their structural stability and resilience against lateral loads. This research work focuses on comparing different types of lateral load resisting systems to determine the most efficient and cost-effective system for resisting lateral loads, such as wind and seismic loads. The study involves a comprehensive review of literature and a comparative analysis of various lateral load resisting systems, including shear walls, belt trusses, outriggers, belt truss + outrigger systems, diagrids, staggered trusses, and tube-in-tube systems. Analysis has been conducted using ETABS-2020 software, considering different methods of analysis for static earthquake forces, dynamic earthquake forces (Response Spectrum analysis as per guidelines of IS: 1893-(Part 1) 2016), and static wind forces as per IS 875 (Part-3)-2015. The design is based on IS: 800-2007 code provisions. The aim of the research is
