Abstract
Above the past two decades, there has been a significant rise in the construction of tall structures over 150m in height, with an almost exponential development rate. Numerous similar structures have been built throughout the Middle East and Asia, and many more are proposed or now under development. Buildings over 300m in height are posing new engineering difficulties, especially in terms of structural and geotechnical design. Wind analysis is critical when it comes to big structures. Figure 1 illustrates the substantial increase in the number of such structures either built or acquired. Because many conventional design techniques involve extrapolation far beyond the boundaries of previous experience, structural and geotechnical designers are being pushed to use increasingly complex methods of analysis and design. Geotechnical engineers, in particular, are progressively abandoning empirical techniques in favour of state-of-the-art methods when designing foundations for super-tall structures. Numerous studies have investigated the structural behaviour of tall structures with SSI by taking into account a variety of factors such as foundation type, soil conditions, lateral stresses, and the ratio of the flexural stiffness of the beam and column. Very few studies on the soil-structure interaction of tall structures in clayey soil conditions, especially in Indian seismic zones, have been conducted. In zone III, a G+18-story rectangular structure with a 3 m floor-to-floor height was assessed using the Etabs software. The selected plan is rectangular in shape. The structure has been evaluated for static and dynamic wind and seismic forces. Structures have been developed for use in circumstances of hard, medium, and soft soil.
