EFFECT OF DIFFERENT SOIL CONDITION ON FOUNDATION DESIGN OF TALL BUILDINGS

In the past two decades, development of tall structures with a height of more than 150m and a nearly exponential rate of expansion has increased considerably. A considerable number of these structures have been built throughout the Middle East and Asia and many more are either under construction or planned. "Super-high" structures above 300m high provide significant difficulties to engineers, especially with regard to structural and geotechnical design. Many of the conventional design techniques cannot be implemented confidently, and require extrapolation well beyond previous experience, and structural and geotechnical developers are thus compelled to use more complex analytical and design methodologies. Geotechnical engineers in particular engaged in the construction of foundations for super-high structures increasingly abandon empirical techniques and use state-of-the-art procedures. A G+18 square building with 3 m floor-to-floor height was assessed in Zone III using the ETABS software. The shape of the selected plan is square. For the structure, static and dynamic wind and seismic forces were analysed. Structures have been built for soil types that are hard, medium and soft.
