Normalized Rotational Multiple Yield Surface Framework (NRMYSF) stress-strain curve prediction method based on small strain triaxial test data on undisturbed Auckland residual clay soils

Prediction of Soil Settlement on Soft Clay Soil Using Normalized Rotational Multiple Yield Surface Framework (Nrmysf)

“…As a result, the average percentage error for Sample CD-A and Sample CD-B decreased from 3.51% to 1.64% and 2.77% to 1.41%, respectively. This similar to the result by [3], [15]. The new framework is capable to predict stress-strain curve better than RMYSF.…”

“…At different values of axial strains, the maximum deviator stresses at failure depend on the effective stresses during shearing, leading to large percentage errors during prediction. The RMYSF method has been refined with a new technique known as the Normalized Rotational Multiple Yield Surface Framework (NRMYSF) introduced by [15]. Table 5 shows that the value of strain at maximum deviator stress was selected and used as the numerator to normalize the data for other effective stresses by using Equation 1.…”

“…In equation 1, the ratio of maximum strains value over the selected strains at failure were calculated. According to these researcher [3], [15], the new framework is capable to predict stress-strain curve better than RMYSF. Normalized = (Max.…”

“…On shallow foundations, the existing methods for soil prediction settlement depend on perfectly plastic soil constitutive behaviour while predicting the immediate settlement uses linear elastic soil behaviour. As a result, these approaches do not accurately reflect the soil non-linear stress-strain behaviour and underestimated the settlement [8], [15], [16], [18]. The actual settlement may differ from the predicted settlement in traditional consolidation analyses due to limitations and unrealistic assumptions.…”
