| Abstract: | A series of tests were carried
out with an eccentrically loaded model surface strip footing on un-reinforced
and reinforced dense sand to investigate the behaviour of the footing (decrease
in ultimate load with increasing eccentricity, failure surfaces and load
displacement relations). The experimental set-up used to run the tests consists
of tank, model footing, sand and loading mechanism. A single woven geotextile
strip sheet was placed horizontally below the footing’s base at a depth half of
the footing’s width. The primary failure surfaces occurred at the eccentricity
side for this laterally unrestricted footing. The use of this reinforcement
increased the ultimate load by about 50% for centrally loaded strip footing in
comparison with un-reinforced case and its contribution to ultimate load
decreased as eccentricity increased in these conditions. Geotextile not only
increased ultimate load, but also increased necessary amount of vertical
displacement of footing to reach failure compared with un-reinforced case. The
experimental results are in good agreement with Meyerhof’s effective width
concept than the customary analysis and the customary analysis is unsafe
outside the core. |
