Random Soil Curve
In Random option, the effects of nonlinear property parameters using the empirical model by Darendeli model are calculated. The variability of soil properties is modelled as a normal distribution. G/G0 and D are generated from the initial curves (mean) and the values are computed as:
- ε1 and ε2 are two non-correlated (pseudo) random variables with zero mean and unit standard deviation.
- are the mean value of the shear modulus and the damping ratio at strain γ
