A Study of Pile Foundation & Raft Foundation for Different SBC

In the recent years, there has been tremendous increase in high rise buildings due to scarcity of space available and requirement of amenities in major cities. Nowadays, construction is even done on refilled areas. But, however, it is a matter of great concern that what foundation will be proposed on such type of natural or man-made refills. Foundation can be classified as shallow and deep foundation, deep foundation are rapidly increasing as that of shallow foundation due to lack of space. The foundation of building is depending on the height, soil properties, testing of soil, loading condition and site investigation. This determines the selection of the foundation for the proposed structure. In the analysis and design of economic foundation for high rise building both geotechnical and structural design aspect are taken into account. Quantitative study has been carried out for different values of Soil Bearing Capacity (SBC). The behavior of structure also depends on soil strata. Sometimes the strata surface is very loose but below it may consist of rock or solid soil. High rise buildings require stronger foundation while short buildings spread the load over the area of the structure. This work includes the design and analysis of Pile & Raft foundation on different SBC that has been discussed in detail on the basis of geotechnical analysis. The design of pile foundation as well as raft foundation is carried out and then the result is compare in manual calculation and software. Programming is prepared in MS-EXCEL. The main aim of the program is to check the manual designing and then comparing the result by putting different values.
