Snap-Back Testing for Estimation of Nonlinear Behaviour of Shallow and Pile Foundations
We are working on the development of methods for analysing the earthquake response of foundations that make use of Soil-Foundation-Structure- Interaction (SFSI) as a means of incorporating nonlinear soil deformation effects and nonlinear geometrical effects into the earthquake resistant design of fo...
