Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...

This paper describes an MPM formulation using linear quadrilateral elements suitable for soil-structure-interaction problems. The volumetric locking and stress-oscillations are mitigated a reduced integration technique the Gauss scheme, respectively. can be used with both structured unstructured computational meshes. In addition, improved calculation scheme is proposed to obtain accurate contac...

The bearing capacity of strip footings on unsaturated soils is studied using slip line theory. The suction profiles considered are non-uniform with depth and correspond to vertical flow of water by infiltration or evaporation. The slip line theory assumes a plastic equilibrium state of a Mohr-Coulomb soil in which suction influences are included using the effective stress concept. This paper sh...

The use of geosynthetic reinforcement to enhance the ultimate load-bearing capacity and reduce anticipated settlement shallow foundation has gained sufficient attention in geotechnical field. improved performance is achieved by providing one or more layers geosynthetics below foundation. full wraparound technique proved be efficient for confinement soil mass reduction however lacks literature a...

The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into the footing. The validation and effectivene...
