“…However, for short caissons, say L f /D < 3, differences between upper bound plastic limit analyses and finite element solutions are greater (Andersen et al 2005) and the database of physical measurements is relatively sparse. While general loading on shallowly embedded foundations with L f /D < 1 has been the focus of considerable attention (Yun and Bransby 2007;Gourvenec 2008) and several noteworthy numerical studies present numerical predictions for the range L f /D = 1 to 5 (Supachawarote et al 2004;Palix et al 2011), experimental validation is relatively limited in the intermediate range of aspect ratios L f /D = 1-3.…”

Geotechnical centrifuge tests were conducted to examine the behavior of low aspect ratio piles and caissons in clayey soils subjected to high moment loading. Model piles with aspect ratio of two were tested in the 150g-ton centrifuge at Rensselaer Polytechnic Institute. Results include moment-inclination and force-displacement response for different loading conditions. Numerical studies were also performed consisting of three dimensional finite element simulations in order to predict capacities. The comparisons are performed in terms of the total resistance that is exerted by the soil on the caisson. This paper focuses on presenting the ultimate bearing capacity factors including both experimental and numerical results. In addition, results are compared to a series of studies available in the literature, which include upper bound solutions and experimental results.
