The behavior of ring foundations on very dense cemented sands was examined by plate loading tests at a flat site located in Kiefan, Kuwait. The effective soil strength parameters c ′ and φ′ were 31 kPa and 36°, respectively. The tests were carried out at a depth of 0.4 m below ground level on 0.6 m diameter solid and ring plates. The latter had inside to outside radii ratio of 0.25, 0.5, and 0.75. The load versus settlement curves for solid and ring plates were compared, with emphasis on the elastic settlement, and on the ultimate bearing capacity. The results indicate smaller settlement at all pressures for ring plates compared with solid plates. However, little or no change in bearing capacity was observed. Tests were also carried out on 0.45 m and 0.3 m diameter solid plates. The purpose being to determine the variation of the settlement ratio with the width ratio for cemented sands.

An analysis of pile axial and lateral response to transient dynamic loading is presented allowing for nonlinear soil behavior, the discontinuity conditions at the pile-soil interface, and energy dissipation through radiation damping and soil hysteresis. In addition, the effect of neighboring piles is taken into account for piles in a group. This analysis is used to derive the stiffness of foundation piles of fixed offshore towers. The effect of foundation nonlinearity and pile-soil-pile interaction on the dynamic characteristics of the tower is investigated. It was found that the tower's dynamic characteristics are greatly influenced by the foundation nonlinearity and the pile-soil-pile interaction. [ABSTRACT FROM AUTHOR]
