this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

This study used finite element analysis to investigate the influence of using two reinforcing systems, geogrid and grid anchor, on bearing capacity a circular footing resting sand. The parameters studied were effect number reinforcement layers (N), depth ratio topmost layer (u/d), vertical spacing between consecutive (h/d), length (L). results showed that layout had very significant behavior re...

We propose a method for computing the energy level spacing around classical string solutions in AdS5 × S5. This method is based on the integrable structure of the string and can be applied to an arbitrary classical configuration. Our approach treats in equal footing the bosonic and fermionic excitations and provides an unambiguous prescription for the labeling of the fluctuation frequencies. Fi...

As a result of the importance foundation in engineering construction, it is important to investigate bearing capacity construction soils, this study therefore investigated soils Ayedaade Local Government Area, southwest Nigeria. To achieve aim study, soil samples were collected from selected 20 sites area. Using standard procedures, preliminary and geotechnical tests such as natural moisture co...

Bearing capacity of soil is an important factor in designing circular footing. It directly related to foundation dimensions and consequently its performance. The calculations for obtaining the bearing a needs many varying parameters, example type, depth foundation, unit weight soil, etc. In this work, comparison between values footing on gypseous before after improvement determined by two diffe...

this paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

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...

In this study, fuzzy logic was implemented to formulate the fuzziness of layer boundaries for a two-layered clay soil. A field of two-layered clay with fuzzy boundaries between layers was generated, and then the bearing capacity of strip footing on this field was calculated by the assumption of plane-strain conditions. The Mohr-Coulomb failure criterion was used and bearing capacity calculation...
