The developments in construction techniques, materials, structural systems and the analytical methods for analysis and design opened the door for the growth of high rise buildings. The race towards new heights and architecture has not been without challenges. Tall structures have continued to climb higher and higher facing strange loading effects and very high loading values due to dominating lateral loads. The design criteria for tall buildings are strength, serviceability, stability and human comfort. But the factors govern the design of tall and slender buildings all the times are serviceability and human comfort against lateral loads. As a result, lateral stiffness is a major consideration in the design of tall buildings. The first parameter that is used to estimate the lateral stiffness of a tall building is drift index. Different lateral load resisting structural systems can be used to impart stiffness and reduce drift in the building. Lateral load resisting systems can take many forms depending upon the orientation, integration and addition of the various structural components. The diagrid structural system has been widely used for recent tall buildings due to the structural efficiency and aesthetic potential provided by the unique geometric configuration of the system. In this study the concept of steel diagrid structural system is studied by conducting literature review, then behavior of structures is studied by comparing square, circular and octagonal buildings with same plan area using ETABS software.
