Pile Capacity from Pile Load Test
Qult = 0.5 (Qult from Chin + Qult from Hansen)
Two conditions should be satisfied from the pile
load test:
I- Qult ≥ 2.00 Qall (D.L. + L.L.)
Dead + Live Loads
Qult ≥ 1.75 Qall (D.L. + L.L. + W.L.)
Dead + Live + Wind Loads
Qult ≥ 1.50 Qall (D.L. + L.L. + Eq.L.)
Dead + Live + Earthquake Loads

Pile Capacity from Pile Load Test
II- Measured d ≤ dmax
max 0.02 D 0.50 * P L
E A
Where:
dmax = maximum pile settlement, (m);
D = Pile diameter, (m);
P = Pile test load, (ton);
L = Pile length, (m);
E = Modulus of elasticity of concrete, (t/m2)
For Bored piles E = 140 ton /cm2 36
A = Pile cross-section area.
