20-Oct-15 Design

20-Oct-15 Design Philosophy of Piled Rafts Conventional Pile Design Method • Disregards the capacity of Pile caps/Rafts • Increased number of piles or length of piles • Very small allowable settlement • Pile factor of safety (FS ≈ 2) Piled Raft Design Method • Raft is the main bearing element • Design for full utilization of pile capacity (FS ≥1) • Piles are Settlement reducers • Consideration of the optimal location of piles to decrease the differential settlement and bending moment of raft. Prof. V.S.Raju Consultants 3 Concept of Piled Raft : • A very good reference “The Piled Raft Foundation for The Burj Dubai – Design and Performance “, IGS-Ferroco Terzaghi Oration – 2008, by Prof.Harry Poulos.
