i have modelled single pile in sand of phi=32 and Esand =25000kPa Unit weight= 19 kN/m3 u(poisson ratio =.25)
PILE PROPERTIES:-
Model-linear elastic
Drainage- non porous
Unit weight= 24kN/m3
Ep=20000MPa
length of pile =6 mts
diameter=0.6mt
as per is code ult load is sand is 850kN(base resistance ) but if i applied 850 kN uniform load(3000kN/m/m) im getting base resistance only 100kN (which is calculated by taking bottom interface stress and multiplied by respective element area).
Anyone plz tell me exact way to calculate base resistance and skin friction for end bearing pile in Plaxis-2D
