Validated numerical approaches are very important in dynamic studies of soil-structure interaction. Experimental outputs of physical models are required to validate the numerical approaches. Testing and analysis of an experimental scaled model is eco...

Numerical Investigation into the effects of cavities on stability of slopes and seepage through earth dams under rapid drawdown condition (2020)
Thesis
Alateya, H. Numerical Investigation into the effects of cavities on stability of slopes and seepage through earth dams under rapid drawdown condition. (Thesis). University of Salford

The stability of dams and natural slopes is a significant and interesting issue and one of the key challenges in the civil engineering field. Cavities forming under earth structures are problematic in the field of geotechnical engineering and may lea...

Response of soil–foundation–structure interaction of tall building (frame-wall) structural system under seismic effect (2019)
Thesis
Qaftan, O. (in press). Response of soil–foundation–structure interaction of tall building (frame-wall) structural system under seismic effect. (Thesis). University of Salford

The unavailability of standards or validated analysis techniques of estimating the soil -foundation-structure interaction (SFSI) lead to either simplifying or ignoring this interaction. The structural and geotechnical engineers consider the foundatio...

Piled foundations could be affected negatively as a result of passive loadings caused by nearby soil movement-induced activities, and failure of piles could happen in some sever cases. This paper deals with the numerical analysis of passively loaded... Read More about Numerical modelling of passively loaded pile groups.

Effect of confinement on the bearing capacity and settlement of spread foundations (2018)
Journal Article
settlement of spread foundations. https://doi.org/10.5281/zenodo.2021831

Allowable-bearing capacity is the competency of soil to safely carries the pressure from the superstructure without experiencing a shear failure with accompanying excessive settlements. Ensuring a safe bearing pressure with respect to failure does no... Read More about Effect of confinement on the bearing capacity and settlement of spread foundations.

Experimental & numerical simulation of soil boundary conditions under dynamic effects (2018)
