Bearing capacity and settlement of circular shallow foundations using a nonlinear constitutive relationship

Bearing capacity and settlement of circular shallow foundations using a non-linear constitutive relationship

The design of shallow foundations is dominated by issues of settlement, rather than by bearing capacity per-se. The ability to predict the settlement of foundations at a given factor of safety is hence of key importance in design. In this paper, the energy method for a linear-elastic perfectly plastic method utilizing the von Mises’ yield criterion with associated flow developed by McMahon et a...

Bearing Capacity of Shallow Foundations on Cohesionless Soils: A Random Forest Based Approach

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...

The Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations

Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

Experimental and Numerical Study of Tension Bearing Capacity of Circular Skirted Foundations Resting on Sand Bed

Skirted foundations are an appropriate alternative to deep foundations in onshore and offshore structures, which have the ability to withstand uplift loads, are also easy to be installed. The tensile performance of skirted foundations on sand was studied by physical and numerical modeling. Laboratory tests were carried out on small-scale foundation models with peripheral skirts. Numerical model...
