An overview on field and experimental evidences concerning seismic liquefaction induced settlement of buildings with shallow foundations

Seismic Bearing Capacity of Shallow Foundations

Settlement Behavior of Shallow Foundations in Unsaturated Soils under Rainfall

Shallow foundations are often situated on unsaturated zones above the groundwater table. In this study, the influence of rainfall infiltration on the settlement behavior of shallow foundations was investigated using numerical analyses. The numerical solutions were compared with experimental data from in-situ load tests. The relative importance of rainfall intensities and groundwater table posit...

An Improved Method for Seismic Site Characterization with Emphasis on Liquefaction Phenomenon

Iran is an active seismic region. Earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. Obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. In this paper, nonlinear geotechnical seismi...

Probabilistic evaluation of liquefaction-induced settlement mapping through multiscale random field models

Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

Effect of footing shape on the settlement of rectangular and I-shaped rocking shallow foundations

Cumulative settlement is one of the primary potential detrimental aspects of rocking foundations. It has been well documented that if the factor of safety against bearing failure is not very large (e.g., less than five or so), settlement can become significant. A series of footings of different shapes were subject to lateral slow cyclic loading on the centrifuge to study the effect of shape on ...
