Review on Performance of G+40 Story Building with Raft and Pile Foundation under Different Soil Condition

The foundation system of a high-rise structure determines its stability, performance under seismic forces, and long-term settlement behavior. Among the various foundation options, raft and pile foundations are widely used depending on the soil conditions and structural demand. This review paper presents a critical study of various published research works comparing raft and pile foundations for high-rise buildings. Emphasis is placed on the effect of different soil types, soil-structure interaction (SSI), seismic behavior, and settlement patterns. A comparative review of more than 13 research studies provides insights into the performance and suitability of each system. The findings aim to support designers in making informed decisions when selecting foundation types for tall buildings.
