Abstract: Seasonal cycles of moisture and suction variation in shallow clay masses create repeating episodes of soil shrinkage and swelling that can adversely affect a wide variety of structures including pavements, shallow foundations, ...

Abstract: This paper presents a cyclic equivalent spring (p-y) model describing lateral soil resistance on offshore well conductors and piles in normally to lightly overconsolidated clays subjected to fatigue cyclic motions. Improved ...

Abstract: Offshore wind energy is an attractive alternative in pursuing the nation's clean energy goals due to the significant demand for electricity in the coastal areas of the United States. Locating sites further offshore in ...

Abstract: Cyclic loading on caisson and pile anchors can be a significant design issue, particularly with respect to cumulative vertical displacements that can lead to reduction in embedment depth and load capacity of the anchor. ...

Abstract: This paper presents an analysis of the load capacity and trajectory of a drag embedment anchor in a soft seabed. Anchor capacity relationships are developed for an idealized anchor comprising a rectangular fluke and a ...

Abstract: Vertically loaded anchors (VLAs) are installed in a manner similar to drag-embedded anchors, except that after initial drag installation the anchor shank is released to enhance pullout capacity. Because of their lightness ...

Abstract: The need for obtaining estimates of undrained shear strength of shallow seafloor sediments often arises in offshore engineering practice. Impact penetrometers offer a promising means of obtaining strength estimates in such ...

Abstract: Fatigue stresses associated with extreme storms, vessel movements, and vortex-induced vibrations are critical to the performance of steel catenary risers. The critical location for fatigue damage often occurs within the ...

Abstract: Embedded plates provide an attractive anchorage alternative for mooring floating structures owing to their light weight and high efficiency. They can be installed through a variety of means, including suction, driving, or ...

Abstract: Although the behavior of shallow foundations under vertical load combinations has been the subject of numerous studies, the response of shallow foundations subjected to combined horizontal and torsional loading has received ...
