Vertical piles subjected to Eccentric Loading

Greetings!

Let's have two cases of eccentric loading on a pile group.

• e is about one axis.

In this case load is given as, Vp = V/n  +- (V.e.xj.A)/Ig

V = Total vertical load on pile group
n = No. of the piles
e = Eccentricity w.r.t.  C.G.(Center of Gravity) of pile group.
xj = Distance of the center of the pile group from center of pile, measured parallel to e.
Ig = Moment of Inertia of pile group about axis normal to axis of eccentricity.

• e is about both the axis

Vp = V/n  +- (V.ex.xj.A)/Ix +- (V.ey.yj.A)/Iy

Where ex and ey are the eccentricities w.r.t. center of pile group, measured along x and y axis respectively.
