Question

Question: Design a square footing foundation of dimensions B that is located 1 m below ground surface level. The soil above the foundation is 18.5 kg/m^3 and the soil directly below the foundation is 18 kg/m^3. The strength parameters of the soil are considered to be undrained. The parameters for the soil located directly beneath the foundation are listed below

Cu = 120kPa and Phi(u) = 0

Determine using the generalised equation listed below, what a suitable dimenions size, B, for a square footing is

qu = rcscdcic(cNc) + rqsqdqiq(qoNq)+ r?s?d?i?(0.5??BN?)

Note, Rigidity, shape factors can be omitted from the design. (State a reason why?)

Therefore

qu = dcic(cNc) + dqiq(qoNq)

Where the loading being applied to the foundation is inclined

Horizontal Force = 900 kN

Vertical Force = 2500 kN

My answer so far:

Im having trouble figuring out which inclination formulas to use. If I use Hansens formulas, I yield an infinite value for iq, which is impossible.

Can anyone help me with this?
THANKS
