ANALYSIS AND DESIGN OF HIGH RISE BUILDING ON A LOOSE SOIL WITH RAFT FOUNDATION USING ETABS AND SAFE

Abstract

In the present scenario a foundation must convey load of a structure and transfer it to subsoil strata with no excessive settlement. Usually practice to initially study shallow foundation arrangement for any building. raft foundation covers the whole projection area of building. At the point when the foundation has satisfactory bearing limit however the settlement isn't inside permissible limit, a pile groups is added the to raft to decrease the settlement. The conduct of raft foundation framework is impacted by different factors, for example, raft thickness, pile length, pile spacing and quantity of piles, which should be must considered for a sparing and economical design. A mathematical study has been done by using geotechnical finite element software, to explore impact of above different variables. The point is to ideally use load bearing capability of the raft foundation. Raft foundation delivers an economical foundation as compared to conventional pile foundations. Minimizing the average settlement and optimizing the depth of raft. Some of existing methods for study of raft behavior offered by different scholars are viewed and their abilities and limits are discussed
