A Review on Seismic Analysis of Irregular Plan of Diagrid Structure on Sloping Ground Sujal Panchal1, Kishan Jayswal2, 1M. Tech Student, L.J.

University, Ahmedabad, India. ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - Modern tall buildings often use diagrid systems
due to their potential for both architectural aesthetics and structural efficiency. Diagrid systems are more structurally efficient than other systems such as braced systems. When a structure can withstand both gravity and lateral load, it is considered stable. Therefore, it is important to design it using structural software such as E-tabs, Staad Pro, etc., to verify certain structural conditions and implementations as per IS standards. The review report takes into account factors such as dead load, live load, floor finish load, wind load, and seismic load as the acting loads. Key Words: Dia-Grid Structure, Structural Design, Seismic Load, E-tabs, Staad pro.

1. INTRODUCTION
The term "diagrid" is a combination of diagonal and grid, used to describe a structural system that uses triangulation to achieve coherence. This system consists of single-thickness members that are joined together at the floor edge beams. The loads, such as weight density and sideways force, are accepted and distributed in a highly distributed manner by multiple members and directions throughout its configuration, resulting in triangulated member evolution.
The current trend shows that the population is growing rapidly, resulting in limited space for new constructions in the city. To accommodate this growth, tall buildings are necessary. The diagrid system is a cost-effective solution that can efficiently resist lateral forces and support gravitational loads. When designing tall structures, it is crucial to consider the lateral loads that can be caused by wind and earthquakes. An inclined column positioned at the periphery of the structure makes the diagrid system a better option for resisting lateral loads. In contrast, diagonal braces in a conventional system can create wall-like structures with widely spaced columns. People living in areas with no flat land are forced to build their homes on hilly terrain. Even though building on hills comes with advantages like great views, natural ventilation, natural drainage, and additional space from lower floor levels, rapid urbanization has led to an increase in the population of hilly regions. As a result, the construction of high-rise buildings has become necessary. However, designing structures on sloping ground is quite different from designing structures on level land due to the changes in mass and stiffness of the building as it rises and spreads.
