- •
A practical method is presented to assess the evolution of failure envelope of shallow foundations subjected to undrained cyclic preloading.
- •
The gradual evolution of soil strain softening and rate effects are monitored and utilised to update the shear strength under cyclic loading.
- •
Soil degradation is detrimental to the capacity of shallow foundations and should be taken into account in design of shallow foundations.
- •
A systematic study is presented to explore the effects of soil parameters and period of cyclic loading on the capacity of shallow foundations.
