People are now rising upward to avoid ongoing urban sprawl and to protect vital agricultural productivity. As the building's height increases, the lateral resisting system becomes just as important as the gravity supporting system. Diagrid has recently acquired favor for tall structures among the numerous lateral stability of tall buildings due to its structural efficiency and aesthetic possibilities given by the system's unusual geometric layout. Because of its triangulated construction, the diagonal components of the diagrid system can support both gravity and lateral loads. For this study, two structural models of 24-story buildings are used: one with a rigid frame structure and one with a diagrid structure. ETABS is used for modeling and analysis of buildings. The analytical findings are compared in terms of story drift and story displacement subjected to lateral loading. When compared to rigid framed structures, diagrid systems are far more effective at reducing drift and displacement. Because of the axial action of the diagonal parts, diagonal configurations carry shear. Shear is carried by rigid-framed constructions due to the bending of vertical columns.

As the height of the building increases, the lateral resisting system becomes as important as the gravity supporting system. In tall buildings, the main problem is that lateral load governs the design, but in the case of a shorter building, gravitational load governs. As a result, when constructing tall structures, structural methods that are more effective at producing stiffness against lateral stresses are preferred. The diagrid structural system is one of the most effective lateral resisting systems due to its different geometric configurations. Recently Structural engineers as well as architects have made significant progress in following diagrid structures. Peripheral vertical columns are omitted in diagrid systems. This is the primary distinction between diagrids and rigid frame structures. In this modern era, diagrid buildings have arisen as a new elegant design for tall buildings, with structural efficiency as a modified form of bracing systems. The triangular geometric configuration of diagrid structures as shown in Figure 1 effectively prevents structural failure due to lateral and gravitational loads.
