Abstract - A diagrid structure is an architectural structure.
It is diagonally intersecting members, usually forming a triangular structure. This design improves safety standards and increases the efficiency of distribution. The Diagrid concept refers to the sustainability and innovation of infrastructure by providing high-performance standards and unique designs in modern buildings. Diagrid structures are commonly used for skyscrapers and other large buildings due to their ability to efficiently distribute loads reduce material usage, and offer a visually striking appearance. The project entails the planning, analysis, and design of an institutional building made of steel materials. The analysis and design process includes structural planning, load calculation, 3D modeling with Etabs. The equivalent static and time history analysis method are carried out in terms of displacement, story drift ratio and base shear using ETABS software and compared to a regular building.

1.1 Advantages of Diagrids
Key Words: Diagrid Structural System, Time History
The advantages of diagrid in building construction greatly enhance the beauty of the building. The use of diagrids can reduce steel by up to 20% compared to frame structure. The construction process is simple. The glass material can shed more light into the structure when used with diagrid. The exterior and interior of these models are mostly column-free and allow the use of customized floor plans.

1. INTRODUCTION The construction of tall buildings is increasing day by day, so safety assessment and construction are required for highrise buildings, as the height of the structure increases, the lateral load is also very important according to the protection structure to carry gravity loads. Structures commonly used for interior structures include rigid frames, braced frames, shear walls, and support structures, while exterior structures include tubular, diagrid, pentagonal, hexagonal, and octagonal grid structures. Diagrid is an exterior structural system in which all perimeter vertical columns are eliminated and consists of only inclined columns on the boundary of the building. The axial movement of these diagonals prevents shear forces and overturning moments from occurring compared to the bending of the vertical column frame tube. Vertical columns in the core are designed for carrying only gravity loads and the diagrid is useful for both gravity and lateral loading.

This type of construction requires technical skill and current workers do not have ideas or knowledge of developing diagrids. A floor design language is achieved by stacking 2 to 6 floors on a diagrid. Only high-rise buildings can install diagrids. If diagrids are not properly designed or installed, it affects the economy and safety of the structure.
