Balises :CPRFSoilAniruddha Bhaduri, Deepankar ChoudhuryPublish Year:2020AbstractThe combined pile–raft foundation (CPRF) has been widely recognized as economic and rational foundation for high-rise buildings when subjected to vertical loading because of its effectiveness in load sharing by both raft and pile components. When a raft alone is unable to bear the load effectively, piles are added primarily to enhance its resistance against failure. Firstly, the piles are constructed and then the raft is placed .Combined pile-raft foundations can be a .1: Bearing Capacity of Combined Piled-Raft Foundation mR, Piles mR, Slab β x σZ mS Sq Rq mR (γ - 1 .

To address this issue, in this research the contribution of the components of pile-raft foundation to lateral loads is evaluated experimentally. Unlike traditional foundations, where the load is supported .A combined pile–raft foundation consists of a raft, a group of piles, and the subsoil (Poulos 2016). Unlike the pile foundation, pier foundations are constructed by excavating or dredging the soil beneath the ground and filling it with concrete and steel reinforcement. The Superstructure loads are shared between the piles using shaft friction and end bearing, while the raft supported on direct soil bearing. The model is numerically simulated in a comprehensive three-dimensional finite element software ANSYS.The second part is to use the hybrid foundation system Combined Pile-Raft Foundation (CPRF), which combines the bearing capacities of the raft and of the piles. A new prediction method is proposed to estimate both Ultimate Limit State (ULS) and Serviceability Limit State (SLS) bearing capacity of CPRF by evaluating the pile-raft and raft-pile interaction factors.
