A four-storey building causes a vertical force 7913.52kN acting on the pile foundation.Can you suggest a design of pile foundation to perform this job. Calculation is based on Meyerhof method for point load and -method for frictional resistance as above. Safety factor is between 3 and 4 and the settlement is within 25mm.Perform the calculation if we use 1600 kN bearing piles piles using Meyerhof method for point load and -method for frictional resistance as above. Safety factor is between 3 and 4 and the settlement is within 25mm.The design should includeThe design is as follows:
Pile Length, Pile Diameter,Structural Capacity (Q all,s), Column Load (Qall), Cu (Layer 3), Number of Piles, Total Vertical Force on Foundation,Target Settlement: <25 mm, Required factor of safety FS: 3 to 4.Point Load Capacity Calculation using Meyerhofs method:
Qp=9ApCu .Frictional resistance using -method as above.Ultimate Load-Bearing Capacity (Qu)=Qp+Qs.Factor of Safety Calculation FS=Qu/Qall.Settlement Calculation:s=QuL/ApEs .
