FLUCTUATING SOIL STIFFNESS IN PILED RAFT FOUNDATON

Abstract: Nowadays piled raft foundations are widely used for the construction of high-rise buildings. Piled raft foundation can be used in both soft and hard soils. In this study, a high-rise building is analysed to estimate the varying effects of soil stiffness on a pile foundation. ETABS software is used for the analysis of superstructure. SAFE software is used for analysis of piled raft foundation. The analysis is carried out to determine the variation of settlements, differential settlements and load bearing capacity of pile and raft with different soil stiffness.

Keywords: Soil stiffness, piled raft foundation, settlements, differential settlements.
