stiffness of piles
i want to model a pile in csi safe program.i define a column spring support and i need to calculate the stiffness of the pile .can anyone tell me how to calculate it?
check out our whitepaper library.
typically the geotech report will give an anticipated length of pile, capacity, and ancipated pile settlement under load. with this information the pile stiffness is easily calculated using two parts:
1. soil stiffness = pile capacity / ancitipate settlement
2. actual pile stiffness = pl / ae with p being the pile capacity, l being the length, a being the pile area, and e being the grout or steel modulus depending on the type of pile being used.
add 1 and 2 and there is your total stiffness. typically the first value alone is adequate as it far outways the second value.
