Deformation mechanisms beneath shallow foundations
Shallow foundations can provide the most economical solution for supporting small-scale structures. The design approach is quite simple considering the ultimate bearing capacity and working-load settlement. Research has shown that settlement calculations, determined using a linear-elastic approach, …

Interaction of earthquake fault rupture with shallow foundations
… with surface infrastructure, esepcially for shallow foundations, and suggested that appropriate foundation design could protect buildings from significant damage.<br/><br/>The focus of this research is to imrpove understanding of the effects of earthquake fault propagation through soil and …

Lateral response of stiff column-supported shallow foundations
… the lateral response of stiff column-supported shallow foundations, resulting from the application of horizontal load on shallow foundations supported by stiff columns, are uncertain. Stiff columns constructed in soft clayey soil have been used to support retaining walls and in such cases, the …

Seismic behaviour of shallow foundations on layered liquefiable soils
… key lifelines.<br/>Settlement and tilting of shallow foundations resting on saturated sandy/silty<br/>soils has been repeatedly observed throughout the world as a consequence of<br/>liquefaction or softening of the foundation soil. Such settlements and tilts can<br/>render structures unusable, …

Air Injection Technique to Mitigate Liquefaction beneath Shallow Foundations
… liquefaction damage that structures on shallow foundations can suffer. Air injection technique has the potential to improve the soil supporting new and existing structures. There is, however, little research on its application and performance beneath existing shallow foundations. The aim …

Long-term Cyclic Lateral Response and Optimisation of Shallow Foundations
… reductions in infrastructure costs, with foundations representing a major share of capital expenditure for both onshore and offshore wind turbines. Current design methodologies for gravity-based foundations (GBFs) have limited capacity to predict long-term cyclic loads. This leads to …

Load and resistance factor design of shallow foundations for bridges
… do not have any LFD provisions for foundations. In this study, a LFD format for the design of shallow foundations for bridges is developed. Design equations for reliability analysis are formulated. Uncertainties in design parameters for ultimate and serviceability limit states are …

The dynamic soil structure interaction of shallow foundations on dry sand beds
The design of shallow foundations located in seismically active zones typically takes a near zero tolerance approach to allowing relative movements between the foundation and underlying soil. This results in a rigid coupling of the foundation with the soil and hence the full transmission of the …

Creep behaviour of shallow foundations on sand and its implication to soil–structure interaction
… literature showing that the creep settlement of shallow foundations on sand can increase over decades to a magnitude comparable to the immediate settlement. However, in most of the existing settlement prediction methods, the creep settlement of footings on sand is either ignored or accounted for …

Soil-Foundation-Structure Interaction in the Earthquake Performance of Multi-Storey Buildings on Shallow Foundations
… in earthquake resistant design. For buildings on shallow foundations, SFSI refers to nonlinear geometric effects associated with uplift of the foundation from the supporting soil as well as nonlinear soil deformation effects. These effects can potentially be beneficial for structural performance, …

Seismic Response of Structures on Shallow Foundations over Soft Clay Reinforced by Soil-Cement Grids
… the dynamic response of structures supported by shallow foundations on soft clay reinforced by soil-cement grids. The soil profile consisted of a 23-m-thick layer of lightly over-consolidated clay, underlain and overlain by thin layers of dense sand. Centrifuge models had two separate zones for a …

ANALYSIS OF THE EFFECTS OF HEAVILY LOADED MAT FOUNDATION ON ADJACENT DRILLED SHAFT FOUNDATION
Construction of heavily loaded shallow foundations adjacent to deep foundation is generally avoided in common geotechnical engineering practice to minimize additional loads on deep foundations. However, with the growing trend of urbanization leading to a demand of new construction, it is not always …

Seismic behaviour of structures with basements in liquefiable soil
… damage in the built environment. Structures on shallow foundations can suffer large settlement and rotation, and light under- ground structures can uplift. The performance of structures with basements, which intuitively combines these two problems, is not understood. In this thesis, the seismic …

Application of lower bound limit analysis with second-order cone programming for plane strain and axisymmetric geomechanics problems
… we firstly investigate the bearing capacity of shallow foundations on sand subjected to combined loading. The results are represented as load interaction diagrams. Secondly, the effect of seismic forces on the stability of inclined anchors embedded in frictional soils and the passive earth …

Estudo da pressão admissível de fundações diretas em solo residual de gnaisse através de provas de carga em placa
… of the allowable pressure of individual shallow foundations resting on grounds of practically instantaneous compressibility. Emphasis was given to the method - developed by Housel (32) and improved by Barata (5, 6, 7, 9) - that permits extrapolation of results from tests on small plates …
