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...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

abstract   statement of problem: hertzian indentation test has been proven to be an efficient and reliable alternative upon vickers hardness test. this method has been used to test dental ceramics, amalgams, glass ionomers and luting cements.there is limited published information about the load-bearing capacity of resin composites using hertizian indentation test. objectives: to investigate the...

In this paper, the effect of footing shape resting on dry sand when subjected to machine dynamic loading is experimentally investigated. A laboratory set-up was prepared simulate case at different operating frequencies. Nine models were tested examine effects combinations two parameters, including frequencies (0.5, 1, and 2 Hz) shapes (circular, square rectangular). The tests conducted under a ...

Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...

The objective of this paper is to develop an analytical equation based on the concept critical-length columns in order optimize ultimate bearing-capacity soft soils, supporting a strip footing and reinforced by group floating stone columns. Optimization procedure was performed three-dimensional numerical models simulated Flac3D computer code, for various soft-soils with different undrained-cohe...

For a reinforced concrete beam subjected to fatigue loads, the structural stiffness and bearing capacity will gradually undergo irreversible degeneration, leading to damage. Moreover, there is an inherent relationship between the stiffness and bearing capacity degradation and fatigue damage. In this study, a series of fatigue tests are performed to examine the degradation law of the stiffness a...

This study aims to increase the bearing capacity of soil by using geosynthetics in a single, double, or triple distribution pattern. The gypseous samples were brought from site near Sawa Lake Al-Muthanna Governorate with gypsum content about (37%), Soil-Model apparatus dimensions (60 × 60 50) cm proposed square footing (10 10) are used experimental program this study. To achieve goal, series (4...
