Raft foundation is essentially a continuous slab resting on the soil that extends over the entire footprint of the building, thereby supporting the building and transferring its weight to the ground. A pile foundation a series of columns constructed or inserted into the ground to transmit loads to a lower level of subsoil. A pile is a long cylinder made up of a strong material, such as concrete. Piles transfer the loads from structures to hard strata, rocks, or soil with high bearing capacity. Piled raft foundations is a combination of pile with raft slab. They are typically used for large structures, and in situations where soil is not suitable to prevent excessive settlement. A raft foundation is often used when the soil is weak, as it distributes the weight of the building over the entire area of the building, and not over smaller zones (like individual footings) or at individual points (like pile foundations). This reduces the stress on the soil. Pile foundation is needed in areas where the structures constructed are large & heavy and the soil underlying is weak. In areas where settlement issues are common due to soil liquefaction or water table issues, pile foundation is a better choice. Pile raft foundations can help transfer loads through weak, compressible strata or water onto stronger, more compact, less compressible and stiffer soil or rock at depth. The addition of piles to a raft increases the effective size of a foundation and can help resist horizontal loads. The analysis of raft, pile and piled raft foundation is been carried out on a G+20 residential structure by using structural software safe 16. Seismic analysis of building is done for a zone factor II earthquake. The paper on studying the G+20 structure for pile, raft and piled raft, it has been observed that the pile raft foundation has reduced the settlement as compared to the raft foundation and it has less upward soil bearing load as compared to the pile foundation.
